I'm trying to organise some content in my space. It would be really useful to have the expanded modal image that pops upon clicking to be a different one than is one the page. (I'd like to provide some expanded information in the popup.) Is this possible, or do you have any other advice for achieving the same thing?
I am assuming you mean the lightbox image that shows when clicking an image embedded in a piece of content. If you are on cloud, there isn't a way to do it except in the case you wanted to have the same information for all images—through CSS.
