Asking for max texture width and height?
Author
My OGL app gives totally white texture if I try to create texture with size of 512x512 pixels. I know that my device can use max. 256x256 textures (Voodoo3, D3DCAPS8 told it). How can I ask for max width & height of texture in OpenGL to resize my texture?
[edit]
And how to know if textures must be sized to power of two? Or can I suppose they must be?

You must use glGet with GL_MAX_TEXTURE_SIZE.
The textures must always be sized to power of two! (except if you use some NVIDIA extensions...)

also u can use gluScaleImage to rescale an image eg from 512x512 -> 256x256
