[AccessD] A2003: Masked bitmaps as button images?

All,

I'm trying to create some pretty navigation buttons for a client.  I
have a great set of icons to use, but cannot figure out how to tell
Access to render each icon's mask color as transparant.

This works like a chamr in VB, of course - but I need it to work in
Access as well!

I thought that the ImageList controls might work, but then I
discovered that although I can put my icons into the ImageList, I
cannot assign those images to any of my buttons.  

I've got to be doing something wrong.  There's no way these features
aren't offered in Access.

Heeeeeelp...
