I'm doing that right now, actually. With at least 1.2.8 (you might have it
earlier, but I don't know) you can use GdkPixbuf, which I found easier than 
imlib. Try something like this:

<code>
GdkPixbuf *buffer = gdk_pixbuf_new_from_file(imgeFileName);
GdkPixmap *newPixmap = gdk_pixmap_new(NULL, someWidth, someHeight, 
        gdk_visual_get_best_depth() );
GdkGC *gc = gdk_gc_new(newPixmap);

gdk_pixbuf_render_to_drawable(buffer, newPixmap, gc, 0, 0, 0, 0, someWidth,
        someHeight, GDK_RGB_DITHER_NONE, 0, 0);

gdk_gc_destroy(gc);
gdk_pixbuf_unref(buffer);
</code>

You can then use that pixmap on a whole manner of widgets. I just used the 
GtkPixmap, which _really_ simple.
