Using Facebook pics as Wallpapers

[Keeper]

Hi all,

I have been trying to use some of my FB pics as my wallpaper but whenever I crop them for the wallpaper the resolution seems to drop and the pics look horrible when set as the wallpaper.

Is there a better way to do this? I am on FB app that comes with DHD, opened the picture in my photos, then 'set as' wallpaper.

Thanks for all your help!
