So,
I took an image that was 1920X1337 pixels at 96 dpi and resized it to 902X800 pixels at 72dpi.
When I copied it to my Dinc2 and tried to use the image as wallpaper, it still brought up the cropping function and I was not able to use the whole image.
Is the dpi (resolution) the issue?
If so, what are the appropriate properties for an image to get used as wallpaper without having to crop it?
I use Gimp 2.6.8
