Sounds like you need to run the EQ2MAPs autoupdater. Map images are all handled via that tool (not actually part of Fetish).
I recently started including all the POI files in Fetish updates to make the install a tad easier for new users, but all the custom map images would bloat the download to much. I'm guessing you haven't run the updater since your last install to a clean directory, which means you don't have the custom map images
