Hi,

I have implemented a new image type called "compound". It allows you
to glue together a bunch of bitmaps, images and text strings together
to form a bigger image. Then you can use this image with widgets that
support the -image option. For example, you can display a text string string
together with a bitmap, at the same time, inside a TK button widget.
