Popup Multiple Image Gallery?

Hello! 

I'm on a Squarespace trial, so I can't link any URL for reference. But I'm working with the GATES template as I'm an artist looking to simply display imagery. 

The GATES template allows for a lot of images, but when you click an image, it simply pops up larger. What I'd prefer to do, is have each image pop up and display a column of images. So each main image on the home page would be clickable to a small popup, , multi-image gallery. Probably just 3 images?

The image below is just a sketch I'm working with. But you can see once the image has been clicked, I get this great little lightbox popup of the full image. If there were 3 stacked images in that popup window I could scroll thru, and then close...that would be perfect! That way I can show the final image and perhaps a couple of process imagery all in the same little window. Almost like each popup is it's own small 3-image gallery. Is this possible?

Thanks for any help!

Another solution would be to create one large "gallery" popup image (instead of 3 individual images) that the homepage image links to, but I can't control the image "thumbnail" on the home page. It auto-creates that and often creates weird crops of the popup image. 

Hi. You can consider using Lightbox Plugin to achieve this.

Let me know if you have any questions.

Did you ever figure out how to do this? I would like to do the same thing on my site.
