Is that a default button that has been reskinned?

Im very new to modding myself, and know almost nothing about the image files and editing them. That being said, have you checked the image name to insure you have it spelled correctly? Caps tend to matter for the most part.

Perhaps if you posted the xml and the image, you may get better help on this.

Hope this helps some.

Edit: Also, you may check to see that you've put the image in the right folder, I've done that in the past trying to hurry thru something lol.
