HD port wallpaper

[lemeiux1]

Ok so I have searched just about everywhere and cant find an answer to this. I am using xbmod's tf3d hd port on my diamond and I want to change the wallpaper, however its not as simple as just selecting an image from tf3d settings.

1. the pictures appear "zoomed" if you will, like it is not the same resolution as the original tf3d (not 480 x 640)
2. No matter what I size the pictures at, they are still zoomed to the same level on my home screen

does anyone know how to resize a pic to make it work with the HD tf3d, or what size it has to be?

thanks a lot!
