Dear Matt,
See gtk_image_set_from_pixbuf() and GdkPixbuf if you want to load the
bitmap from a file.
See gtk_image_set_from_pixmap() and gdk_draw_rgb_image() if you want to
get the image data from some RGB buffer. You also need to create a
pixmap with gdk_pixmap_new(). GdkPixmaps are GdkDrawables, and so a
pixmap may be passed to gdk_draw_rgb_image() with the GDK_DRAWABLE()
cast.
Make sure to read the docs for the above functions. They are spread
around:
gtk_image_*: GTK+ docs (under GtkImage)
gdk_draw_rgb_image: GDK docs (under GdkRGB)
gdk_pixbuf_*: gdk-pixbuf docs
gdk_pixmap_*: GDK docs (under "Bitmaps and Pixmaps")

I am new to gtk and trying to draw a bitmap to the screen. the bitmap is
about 200 by 300 pixels with 8 bit rgb, total is 24 bits. alpha is
optional at the moment. for now it is 0xff. i have tried many different
examples from the internet but none seem to work. can anyone give me an
example ? maybe just draw it once to get me started or put it in a timer
loop to be called when idle ?
thanks, matt
