Look into loading TGA files. There is a tutorial about it here.

hey bob, "I can't get anything to work" includes that NeHe tut, well it works, but then I can't get my own tga pics to work.
It keeps saying must be type 2 or 10 but I don't know what that means

Ahh...So, it loads other people's tga files, but not yours? Well...Are you saving them in the correct way? (NeHe's tut needs RLE compression, make sure you aren't using anything else if you are using similar code).

1) What program are you using?
2) What attributes are you setting?

I found a free program PhotoFiltre... I can make a certain colour transparent, I can make the colour rgb OR indexed (up to 256 colours & diffuse is an option) that's about it

Try infraview or the gimp. TGAs don't use color transparency, they have alpha channel support for that.
