Long story short...can I import some image(jpg, gif, what ever) into BES and then push it to the device and force the device to use it as it's wall paper?
(if someone know what the specs are for what the wallpaper needs to be that would be helpful)

I'm pretty sure I could build a whole theme and go that route correct?

I would rather not do that. The powers that be would like the field devices to have a company logo for the wallpaper.

Is there an fairly easy way to do this from BES?
