Hi Stephen. AFAIK there isn't a method for easily identifying " orphaned " images. Might make a good Suggestions & Ideas . As far as retrieving your images from roll20; In Chrome, open the campaign editor, open the Developers Console( ctrl+shift+J ) | Resources tab | Frames | app.roll20.net or app.roll20dev.net | Images . Find your image in the list, in the main console window, right-click the image and "copy img url", paste into a new tab and change the name of the file from "med" or "thumb" to " max " and download.
