Hi, thanks for the reply! You just helped me understand that I can delete the default "grid" section that Squarespace auto generates on the main portfolio page...then add a new section/block with a blank masonry style gallery like you shared, and link each gallery image to the corresponding project url within the portfolio. This is a great work around, so thank you!
But, I still would love it if I could avoid this manual work, and just customize the design of the default section that Squarespacae creates for each new portfolio, with all of the urls auto generated. If you, or anybody has any other ideas on how to do this I'd greatly appreciate it. Thanks!
