Nice guide, but please note then when you still use the TBC client (for private servers etc.) the size will have to be 256x256. The 512x512 texture and image support was added with the WOTLK client. You can also use the 256x256 size on a WOTLK client.

Also, it's possible that you won't see the texture because the *.blp filesize is just too big.
