  and I think that then, you may (should? I am not sure)  put the
GdkPixmap in a Widget using 


GtkWidget* gtk_pixmap_new     (GdkPixmap  *pixmap,
                               GdkBitmap  *mask);


  the "mask" arg comes from :

  mask = gdk_imlib_move_mask(imlib_image);


  I think it can be NULL, but since I use the perl bindings, I am not
sure what it is in C.

  You may change the GdkPixmap in the widget by doing


void       gtk_pixmap_set        (GtkPixmap  *pixmap,
                                  GdkPixmap  *val,
                                  GdkBitmap  *mask);


  I hope that helps.

ps: If I said nonsense, please let us know : I use (the perl bindings
     of) these functions, but without really knowing why it works.



pps: My impression is that 

   GdkPixmap          *gdk_imlib_move_image(GdkImlibImage * image);

"gives" the memory allocated for the GdkImlibImage to the GdkPixmap,
whereas 

   GdkPixmap          *gdk_imlib_copy_image(GdkImlibImage * image);

does a copy.
