Each graphics program has its drawbacks and advantages. You can't use Paint Shop Pro for map-making tga files, and you can't use GIMP for bmp skins apparently.

Isn't it always something?

I haven't found anything I can't do with gimp yet, you just need to grab a format converter for skins. Brighter is easy to use, free, and does a great job.
For skins just click 'save as' in gimp, save it as 28bit windows bmp, open that file with Brighter and send it where you want it *POOF* you have a new skin! :wink:
