I finally got back onto dealing with this. I think I like your script, but I'm having trouble getting the finder to load -- it finds the new icon, when I click on it, the pop-up opens, but the URL nets a 404 error. Ditto if I do it using a select field. I cannot see what is being generated from the icon in the editor. What is being created for the select is https://dev.fnps.org/fuel//assets/select/images (fixing the double // does not help). What I don't know is what the URL should be. Any hints would be appreciated.
