Hi Duarte,

I had a similar problem lately. I wanted to draw a raw image I got from
my vision libray onto a GtkImage widget. The way to do this is:
- draw raw image onto an offscreen buffer (a GtkPixmap)
- then draw buffer onto the GtkImage
See the inclosed part of code for more information

The only thing I can't tell you, is how you'll get the jpeg onto the 
GtkPixmap.

One strange this I have come across is that this sometimes hangs if the
draw onto the GtkImage happens at the same time as a redraw (eg. when the 
window
was covered and is expoed again). Has anyone an idea how to solve this?

cu.
