As I see it, you want to display PIXMAPs in a window (or on a widget).

>How do I use them?
So what you do is first create a IMAGE. This is the way to tell X about
the 'look' - this is depth, colors, etc. - of you image. Second you puts
the image into a PIXMAP (you could clip the image, if needed, at this point),
and use this pixmap on the window (or in a widget).

Before you write the code for this, you should look at XPM format and 
functions - These are publicdomain from Bull.

I'll hope this would help you. Mail me if you need further help.
