I have a related kind of problem. When preparing notes for a class, I may end up with 70 code blocks in an org file, many of which create graphics. I am always worried about accidentally using the same filename and overwriting a graphic from an earlier block. A unique, but reproducible filename would be sufficient for my needs.
