The procedure I have found to be successful is the following:
0. ignore the icon stack, and don't bother editing "my icons"
1. Create a substack to hold the icon images you want to use
2. Import the image you want into this substack, taking note of the
image id (yyyy).
3. Create your button xx.
4. Type in message box, "set icon of button xx to yyyy" (image id)
Note that MetaCard has some obscure rules for image id's. I think they
reserve everything under 1000 for their own icons and images. Also I've
had some core dumbs if I try to remove an image that some button uses as an
icon. I think this is an area which needs some clarification. Perhaps the
"icons..." dialog needs to be improved to easily allow for custom icons.
(Something I have had some difficulty with)
