I think you need to get ahold of some docs that lists the function parameters of all OpenGL functions, or you can at least look at the GL.h header file and find out what each parameter takes:
OpenGL is only a graphics API. You have to handle the loading of image data yourself.
There are plenty of sites out there that have tutorials for doing this. Off the top of my head, check out http://nehe.gamedev.net. He has quite a few good tutorials.
