There's some code in vips scalar to add a file comment about file source for jpeg files, however there is none for pngs. Currently image magick adds something along the lines of: Comment : File source: http://commons.wikimedia.org/wiki/File:Organizational-examples.png (among a host of other things). Not the biggest deal, but would be nice to fix.
