Editing WoW:XML/Texture (section)

=== Images ===
Textures are the means to display images in the game. The image must be either a [[TGA file]] (http://en.wikipedia.org/wiki/Truevision_TGA) or [[BLP file]] (http://en.wikipedia.org/wiki/.BLP) image file. Textures may only load images whose dimensions are powers of two, such as 2x2, 4x8, and so on. Images that have non-power of two dimensions will show up as solid green textures. The image does not need to be square, however, so rectangular dimensions like 32x128 are also valid.
