You can assign an image to each panel by double-clicking the panel and uploading the image. It does the masking through svg. You can then save off the SVG by going to preview mode and saving. Sorry that wasn't intuitive. TBH I was trying to prioritize a minimal, efficient, and effective workflow over first-time intuition. Another person suggested I make an instructional video, which is probably a good idea. I'll try to do that this evening when I'm free.

Thanks for the explanation. Single clicking on a panel and then clicking open on an image wasn't working for me.

This is awesome! I wanted a way to make a photo collage of our dog for my girlfriend and this looks like a great way to do it. Thanks for sharing!
