Display image to fullscreen via shell

Hello everybody,

I am running Qtopia on an Mini 2440 Arm9 Board with 7"
and my goal is to display an image on fullscreen via shell command.
if i for example enter "photoedit bild.jpg" photoedit openes and displays
the picture, but i cannot achieve it to be displayed on Fullscreen.  

My Question is if there is any possibility to do that easyily or do i have
to write a small Qtextended Application? Or howto use the framebuffer on
mini? which images? 
If so, how would it have to look like?

i would be happy about any anser :)

best regards
