I'm using a VBA userform to build the front-end to a weather model. I
have a GIF of a province split into regions. The region names reside
in a listbox. When a user chooses region(s), I would like to display
that region on the provincial GIF in a different color. I've read
that imagelist has a image overlay method, but haven't found any
information on how to implement it.

thx.
Edward
