This works just fine, but the problem is images referred to from within these existing files. The images are located at the same level as the html files and appear correctly when I view the html version of the help. But are missing from the Qt help. I assume this is because they're not listed in the <files> section in the Qt Help Project file (.qhp). A workaround is to manually edit the .qhp file and add all images files, but is there a way to get doxygen (or Qt) to do this for me?
