What you can do about this, is two things:
Resize the .pg to meet you req.
Then go to "skin.ini" and look for the "main menu" entry, change to lower number and after that you will see the buttons.
So to explain better the way that the main menu works is to be right on top of the audio menu, so if you have a smaller .jpg and change the number in the .ini you will acomplish what you want.
I just did this to my new skin and it works perfect.
