scope of gRevAppIcon on substacks

[Dr. Hawkins]

I'm trying (finally) to use gRevAppIcon, which displays an icon in ask &
answer.

It seems that this uses the *short* id of the image, which would seem to
limit it to the stack in which it occurs (or possibly to the main stack).

I've set it as a global in my mainstack, and it is used in the test answer
that follows--but then it does not appear in the list of global variables.

Do I need to have this image lurking in every stack?  that sounds like a
maintenance nightmare . . .

Or am I doing something wrong?
