Certain image files use other formats. The startup logos use .jpgs but I guess they're pretty irrelevant. Targa (.tga) is the main format used for GUI images and icons. DirectDraw Surface (.dds) is mainly used for model textures, planes and other 3D environmental objects. You can use Gimp or Photoshop to export either, DDS with the help of a plugin. Paint.NET also has built-in support for DDS.
