Setting a wallpaper issue

[DiamondJay20]

so on my other Android devices, and sometimes on the N7, I can chose how to center the wallpaper when I set it. But on my Nexus 7, I can't with gallery, so the default home screen (middle) is off center. The only time where it worked correctly was a photo i got on bluetooth. How can this be fixed?

I've noticed the same problem when setting wallpaper through gallery.
but when using a third party program, it sets it properly.
