Looking at the error, it seems that the length of the sides of the image aren't powers of two. That's all the help I can offer

You have to make size of picture in size of 2 so 128x128 or 64x128 or something like that. Make it that size and reply.

I guess its a 2d image .. you know something on the hud or whatever, make sure you set materialType to 2d.

If its a texture for something, make sure its set to model phong or world phong and add a normalmap texture.

like so
