Update 5/26/2020: Squarespace has added the ability to add image descriptions/captions to 7.1 gallery sections. See here. There are some limitations, such as not appearing in lightbox view and not supporting multiple lines. So, the workaround below may still be of use.

Hi @dan3.
Looking at the underlying gallery code, it appears that image descriptions are in-the-works to one degree or another. In the mean time, I've created a bit of code you can use to add image descriptions/captions to gallery sections in Squarespace 7.1 .

JavaScript
Insert via sitewide footer code injection. If you only want to add descriptions to some (not all) galleries, pass your own CSS selector into addGalleryItemDescriptions() (for example: "section[data-section-id='5db1f73f7a30760db464bb02']") For images within a targeted gallery that you do not want a description to appear, you must enter a space as the description (otherwise the filename will show). <script> /** * Add descriptions/captions to galleries in Squarespace 7.1. * JavaScript * © @brandon (Squarespace Forum User) * This software is provided "as is", without warranty of any kind, express or implied. */ document.addEventListener("DOMContentLoaded", function() { addGalleryItemDescriptions(); function addGalleryItemDescriptions(gs, gdzs) { var a=['querySelectorAll','section.gallery-section,\x20.gallery-lightbox','length','[class*=\x27-item\x27]:not([class*=\x27item-\x27])','getElementsByTagName','img','alt','trim','createElement','div','className','gallery-item-description','textContent','appendChild'];var b=function(c,d){c=c-0x0;var e=a[c];return e;};(function(c,d){var e,f,g,h,i,j,k;e=document[b('0x0')](c?c:b('0x1'));i=e[b('0x2')];while(i--){f=e[i][b('0x0')](d?d:b('0x3'));j=f[b('0x2')];while(j--){g=f[j][b('0x4')](b('0x5'))[0x0][b('0x6')][b('0x7')]();if(g){h=document[b('0x8')](b('0x9'));h[b('0xa')]=b('0xb');h[b('0xc')]=g;f[j][b('0xd')](h);}}}}(gs,gdzs)); } }); </script>  
CSS
Insert in "Customer CSS", via the CSS Editor. The CSS below is very basic, adding a white box around the description and generally placing it at the bottom. You can customize to your heart's content. /** * Add descriptions/captions to galleries in Squarespace 7.1. * CSS * © @brandon (Squarespace Forum User) * This software is provided "as is", without warranty of any kind, express or implied. */ body { width: 100%; } section.gallery-section [class*='-item']:not([class*='-item-']):not([class*='-reel']):not([class*='-slideshow']) { position: relative; } .gallery-item-description { font-family: "Roboto", sans-serif; font-size: 16px; color: black; } .gallery-grid, .gallery-strips, .gallery-masonry, .gallery-reel, .gallery-fullscreen-slideshow { .gallery-item-description { position: absolute; width: 100%; bottom: 0; background-color: rgba(255, 255, 255, 0.7); padding: 2% 6%; box-sizing: border-box; } } .gallery-slideshow, .gallery-fullscreen-slideshow, .gallery-reel { .gallery-item-description { padding: 10px 25px; opacity: 1; transition: opacity 0.2s; } .gallery-slideshow-item:not([data-in="true"]), .gallery-fullscreen-slideshow-item:not([data-in="true"]), figure[style*="-9999"] { .gallery-item-description { opacity: 0; } } } .gallery-slideshow { .gallery-slideshow-list { position: static; } .gallery-slideshow-item-wrapper, .gallery-item-description { flex: 1 1 auto; } } .gallery-reel { .gallery-item-description { text-align: center; left: 50%; transform: translateX(-50%); } &[data-width="inset"], &[data-width="inset"] { .gallery-item-description { max-width: 88vw; } } &[data-width="full-bleed"] { .gallery-item-description { max-width: 100vw; } } } .gallery-lightbox .gallery-item-description { margin-top: 1em; padding: 1em 2em; background-color: rgba(225, 225, 225, 1); transition: opacity 0.1s ease-out; } .gallery-lightbox-item[data-in=false] .gallery-item-description { opacity: 0; } This is of course experimental. Do let me know how it works for you, or if you have questions.
If you reply to this post, please do not quote the code in your reply. Doing so will create copies of the code which A) I would prefer not be copied and B) will propagate old versions of the code which are likely to fall out of date.

This is an update to let you know that I've added just a couple lines of CSS to fix the issue with the lightbox caption delay/lag issue. The lines are added at the end of the CSS in the original post. They are:
transition: opacity 0.1s ease-out; .gallery-lightbox-item[data-in=false] .gallery-item-description {   opacity: 0; } Special note to those who mentioned the issue: @kinapark , @IvanOB , @ed.design , @JohnS123

You can do it in a number of ways:
Use a form (or newsletter block) to collect their email address, and provide the link to the download on the post-submit page. The downside with this option is that they could input a fake email address and they'd still see the download link. Use a form to collect their email address, send their details to a mailing list service (such as MailChimp) and configure the mailing service to email them the link. Embed a third party service that offers this feature (for example, Salesforce).

Hi @emmaj.
A1: There are a couple ways to do this. The JavaScript is setup so that you can pass in your own CSS selector. That allows you to set which galleries get descriptions (by default, all of them do). In your case, it sounds like you only want to select gallery lightboxes. So replace this line in the JavaScript:
addGalleryItemDescriptions(); with
addGalleryItemDescriptions(".gallery-lightbox"); An alternative way (instead of the above) would be to simply leave the JavaScript alone (so all galleries would still have descriptions) but then hide it on certain galleries using CSS. You'd use your browser's inspector/developer tools to find the correct selectors and write the CSS. Something like this might work:
section.gallery-section .gallery-item-description { display: none !important; }  
A2:
.gallery-item-description { text-align: left; }  
A3:
This would technically be possible by using the image file name as the title. You'd be sure you name your file "This is my title.jpg", then the JavaScript component of the code I wrote could be amended to add that as the title (minus the file extension ".jpg".). That'd take a fair bit of additional custom development time, but it is possible.
 

Hey @Meeeee. Paul can certainly clarify if/when he can, but at the bottom of the page it says: "The wishlist cannot be used in conjunction with the cart/checkout. It completely replaces the cart and is designed for websites that do not take payments online (sales or donations)."

Hi @CindyC
I've produced a wishlist extension for Squarespace that may suit your needs. It replaces the cart with a "wishlist" list that potential customers can submit to you, allowing you to reply with a quotation or invoice.
Please take a look at it and direct message me if you have questions 🙂

So, who might be in charge for the implementation of this to all Squarespace websites?

We need it so badly, all Squarespace sites are illegal with the old cookie consent right now,
the only legal solution in the EU as of today is to switch off all cookies,
which is such a bad idea when it comes to all things marketing & analytics.
Dear @yoshe are you involved in this?

Oops! I meant why gradient as opposed to a solid HEX color alone. I wasn't clear. I realize the gradient rgba has it completely translucent, so I see now that it's transparent, then solid. This is def cleaner than what I thought in my head.

It's almost always best to provide the URL to the site/page in question along with the view-only password if necessary (for sites in trial mode, etc.). However, in this case you may not even have an example page setup.
Here's an example in Brine which I whipped up.
It uses "card" style image blocks in a single index section/page. Of course, your page ID would be different, and you'd probably want to more specifically target the section. You'll also want to mess with the padding on the text in order to get it where you want.
You could do the same thing with regular 'ol image and text blocks and would probably have a bit more flexibility, but I figured this was good enough to serve as a proof of concept for you so as to answer your question, "yes".
#page-5d9e40adc1c17f087e491930 { background: ~"linear-gradient(#BBB, #BBB) no-repeat center/1px 100%"; /*https://stackoverflow.com/a/53551089/5338581*/ } .design-layout-card .intrinsic { padding-top: 50px; padding-bottom: 50px; } .design-layout-card.image-position-right .intrinsic { padding-right: 6%; margin-left: -6%; background: linear-gradient(90deg, rgba(0,0,0,0) 40%, #FFC0CB 40%); } .design-layout-card.image-position-left .intrinsic { padding-left: 6%; margin-right: -6%; background: linear-gradient(270deg, rgba(0,0,0,0) 40%, #FFBB22 40%); } .sqs-block-image .design-layout-card .image-card-wrapper { background-color: transparent; } Do let me know how this works for you.

Yes, @hmfedders. You could do something like this, which would hide the description in a specific gallery on every-other item:
[data-section-id="5db2f35f9ff0e37436549a65"] .gallery-grid-item:nth-child(even) .gallery-item-description { display: none; } Or you could target a list of gallery items individually by using their data-slide-url attribute:
.gallery-grid-item[data-slide-url="1m274ar58gglbeuorp6quol3tmkhel-lx99y"] .gallery-item-description { display: none; } Do keep in mind that in the above examples, the data-section-id and data-slide-url would need to be changed to match your website. You can obtain these attributes using your browser's developer tools/inspector.

Update 5/26/2020: Squarespace has added the ability to add image descriptions/captions to 7.1 gallery sections. See here. There are some limitations, such as not appearing in lightbox view and not supporting multiple lines. So, the workaround below may still be of use.

Hi @dan3.
Looking at the underlying gallery code, it appears that image descriptions are in-the-works to one degree or another. In the mean time, I've created a bit of code you can use to add image descriptions/captions to gallery sections in Squarespace 7.1 .
View Demo Site
JavaScript
Insert via sitewide footer code injection. If you only want to add descriptions to some (not all) galleries, pass your own CSS selector into addGalleryItemDescriptions() (for example: "section[data-section-id='5db1f73f7a30760db464bb02']") For images within a targeted gallery that you do not want a description to appear, you must enter a space as the description (otherwise the filename will show). <script> /** * Add descriptions/captions to galleries in Squarespace 7.1. * JavaScript * © @brandon (Squarespace Forum User) * This software is provided "as is", without warranty of any kind, express or implied. */ document.addEventListener("DOMContentLoaded", function() { addGalleryItemDescriptions(); function addGalleryItemDescriptions(gs, gdzs) { var a=['querySelectorAll','section.gallery-section,\x20.gallery-lightbox','length','[class*=\x27-item\x27]:not([class*=\x27item-\x27])','getElementsByTagName','img','alt','trim','createElement','div','className','gallery-item-description','textContent','appendChild'];var b=function(c,d){c=c-0x0;var e=a[c];return e;};(function(c,d){var e,f,g,h,i,j,k;e=document[b('0x0')](c?c:b('0x1'));i=e[b('0x2')];while(i--){f=e[i][b('0x0')](d?d:b('0x3'));j=f[b('0x2')];while(j--){g=f[j][b('0x4')](b('0x5'))[0x0][b('0x6')][b('0x7')]();if(g){h=document[b('0x8')](b('0x9'));h[b('0xa')]=b('0xb');h[b('0xc')]=g;f[j][b('0xd')](h);}}}}(gs,gdzs)); } }); </script>  
CSS
Insert in "Customer CSS", via the CSS Editor. The CSS below is very basic, adding a white box around the description and generally placing it at the bottom. You can customize to your heart's content. /** * Add descriptions/captions to galleries in Squarespace 7.1. * CSS * © @brandon (Squarespace Forum User) * This software is provided "as is", without warranty of any kind, express or implied. */ body { width: 100%; } section.gallery-section [class*='-item']:not([class*='-item-']):not([class*='-reel']):not([class*='-slideshow']) { position: relative; } .gallery-item-description { font-family: "Roboto", sans-serif; font-size: 16px; color: black; } .gallery-grid, .gallery-strips, .gallery-masonry, .gallery-reel, .gallery-fullscreen-slideshow { .gallery-item-description { position: absolute; width: 100%; bottom: 0; background-color: rgba(255, 255, 255, 0.7); padding: 2% 6%; box-sizing: border-box; } } .gallery-slideshow, .gallery-fullscreen-slideshow, .gallery-reel { .gallery-item-description { padding: 10px 25px; opacity: 1; transition: opacity 0.2s; } .gallery-slideshow-item:not([data-in="true"]), .gallery-fullscreen-slideshow-item:not([data-in="true"]), figure[style*="-9999"] { .gallery-item-description { opacity: 0; } } } .gallery-slideshow { .gallery-slideshow-list { position: static; } .gallery-slideshow-item-wrapper, .gallery-item-description { flex: 1 1 auto; } } .gallery-reel { .gallery-item-description { text-align: center; left: 50%; transform: translateX(-50%); } &[data-width="inset"], &[data-width="inset"] { .gallery-item-description { max-width: 88vw; } } &[data-width="full-bleed"] { .gallery-item-description { max-width: 100vw; } } } .gallery-lightbox .gallery-item-description { margin-top: 1em; padding: 1em 2em; background-color: rgba(225, 225, 225, 1); transition: opacity 0.1s ease-out; } .gallery-lightbox-item[data-in=false] .gallery-item-description { opacity: 0; } This is of course experimental. Do let me know how it works for you, or if you have questions.
If you reply to this post, please do not quote the code in your reply. Doing so will create copies of the code which A) I would prefer not be copied and B) will propagate old versions of the code which are likely to fall out of date.

Hey @alicroft.
This can be done. It requires a short bit of JavaScript to look for the "updated-at" div, query the page's JSON data, find the latest updated collection for the page (or series of pages in the index page), format the date to your liking, and then write the HTML to the "updated-at" div accordingly.
I'd guess it'd take a good dev. and hour or two to write and test an efficient and resilient script to do that (the first half hour to get the "gist" done, then maybe another hour to mess with time formatting, which takes a bit of time without using 3rd-party libs).
So yes, it's possible. Having taken a quick look, I think it could be done without you having to refactor your code at all. You could leave it as you have it on the pages you want it to appear, and the code could be set to run on those pages. If you want more info or help, say the word.

Hi @NuprinBoy.
You understood correctly. You can control which galleries get descriptions by sending a CSS selector to the function. In your case, try this: In the first line of code in the function replace
addGalleryItemDescriptions(); with:
addGalleryItemDescriptions(".gallery-lightbox"); If that doesn't work, provide a link to the site/page in question and I'll take a look.

@EllieC: You mentioned that you do not have an account that allows adding custom code. Therefore you cannot add it via a code block either. That is why I mentioned the Markdown block (not the code block).
