For what it’s worth, I also found another way of doing things.
This post is fascinating. He’s doing some really cool stuff with javascript in an html element. One of the neat things I learned is that you can put the entire base64 content of an image into a “link”.
So something that did technically work for me was to upload the base64 into a thing’s text field with “data:image/jpg:base64,” concatenated onto the beginning. Then I put that text into an html element with this code "<img src="search for whatever:first item's text field" width="200px"/> It’s ugly and clunky and slow, but it’s an option.
