Comment 6 for bug 296414

You couldn't even install GIMP on the server. It's a GUI (GTK) application, so it probably wouldn't compile, run, or install with a deb on the server.

The important factors are Drupal, imagefield, and ImageMagick

Imagemagick handle's pdf, and i think odf. Imagefield does not, and I would have to figure out how to trick it into accepting PDF and ODF, since they are not technically images. The main problem with allowing them is that it will error out and say that the MIME type isn't right. That starts to get way outside of my field of expertise.
