Can you create client galleries for proofing/download in Squarespace?

Is there a way you can easily upload secure client galleries to squarespace? 

If not, is it possible to create a page to link to Zenfolio, where you can create client galleries?

I've been wanting this too, especially if it could pull the images for preview from dropbox. That would so so so good.

Have there been any updates on this topic? As a photographer, I may have to change over to Pixieset to get this functionality that clients are wanting (e.g., I upload client images to my website (gallery), email client access link and they can download hi-res images from my site). 

I am getting ready to launch a new site and it looks like I will have to do image-proofing done through Shootproof.  There are a lot of little things that have made me rethink the site the shopping experience seems very clunky. I wanted to set up a 50% deposit to hold studio time, well that can't be done easily you need to use the new project management section, but that is not a customer-facing interface.  I already have an outside service that lets me send contracts and quotes that once signed turn into an invoice and allow online payment, In order to add a deposit you have to subscribe to one of these buy now pay later services and they take between 7 and 9 % plus 50 cents for each transaction.  I don't want another subscription we are being forced into them.  I looked at Woo comm. and they are the same way there is a WordPress plug-in to allow deposits.  I come back to Squarespace because I don't have to deal with broken plugins every time there is an update.
