I'm wanting to make a collage for my blog posts.

This other Squarespace photographer did it, and im wanting to know how to do it?! Can you please help me. Here is another photographer that is doing the same.

The first one has been done the ‘correct’ way, adding each image in its own Image Block and then dragging and resizing them into position. The second link is not ideal. Each ‘row’ is a collage of images edited in an image editor before being loaded into image blocks. This causes issues with margins (see the different gaps).
