glBindTexture(GL_TEXTURE_2D, textures[3]); 
     textureData = LoadBitmapFile("rockstileable.bmp", &textureInfoHeader);
     glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);
     glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
     glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, textureInfoHeader.biWidth, textureInfoHeader.biHeight, 0, GL_RGB, GL_UNSIGNED_BYTE, textureData);

It compiles, but when i run the program, I get a runtime error and the program won't run. :( rockstileable.bmp is definitly in the right location, but I don't know why I'm getting this error. I load a bunch of other .bmp files , but this one is causing trouble. :(

It's probably because it's called rockstileable.bmp :)

Seriously, that's all we know about it, and that's not nearly enough information to debug this one.

Is there no error checking in LoadBitmapFile? Is this your own function (in which case you should debug by stepping through it)?

The .bmp might be corrupted, or it may be in a format that you don't support (like 256 color), but theres no telling just by having the name of the file in a short code snippet.

I recommend stepping through it with your favorite debugger (or just checking the stack trace) to find out exactly which line is causing the error. This will greatly aide your bug-finding.
