Can a texture be any size? If not, how can I load an image of a specific size, say.... 640x480? thanks!

The texture''s x and y must be powers of two. Scale your textures to a 2^n*2^m size!

You can use non-power of two textures by making them mipmaps. However even on the lowest level the computer will size it to a power of 2 texture.

if u felt that u wanted to uses a non 2^n*2^m size! texture you caould always uses subtexture which doesnt care bout the size and is faster or so says the red book than actually doing a normal texture
