raw image file

Is raw the best image format to use as a texture in opengl? Can you tell me why or give me an other good format and explain how to load it?

I usually use TGA files, because their ability of having an alpha channel.
At the following site you can see some examples of tga-loading texture classes.

Hope this helps,

Thanks for your answer, I think I will use TGA!
