In theory all textures need to have their width and height based on a power of two (2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, etc.) in order to display correctly.

What most 3D programs do is they load the bitmap that you wish to use and if it is not at a power of two it will scale the width and height down to the closest power of two.
