Have you made sure than your texture dimensions are power-of-two? And that they aren't larger than whatever your card can handle? Just a thought.

thanks everyone for all their help. I finally got it to work. I used a lot of stuff from the epee engine so I thank the author for the simplest opengl code ever.

Right now I'm loading png's with an alpha layer of transparency. OpenGl seems to be ignoring the source alpha in the images. Anyone know how to turn that on?

thanks

glBlendFunc ( GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA );
glEnable ( GL_BLEND );
