Yeah please tell us what system you're using. If you're on a Mac then Graphic Converter handles them nicely. Heh Graphic Converter handles everything.

Any decent (and some not-so-decent) photo/graphic-editing program oughta handle TGA files. I recommend converting them to JPG, though, they take far less space that way.
