Hmm, I didn't think of that.. Here's what I got with my camera statement:
The size of the visible area goes from -1 to +1 always.. When I load an
image that has a size of <106,135> and I want to scale it, I use this
variable:

#declare Pixels=2/<image_width,image_height,0>;
scale <106,135,1>*Pixels

Similar if I want to move it, by so many pixels... It's very easy.. Now,
that I finally got it to work. ;o)

Thanks,
Hugo
