I see what you are saying, but I was hoping it would be something as
easy as the tool "fill with a color gradient", and using the "fg to
transparent" gradient.  Instead of fg color it would be fg image, or
something like that.

What I had in mind would be quite complicated doing it one pixel wide at
a time because of the size.  Nifty idea though.

I will keep playing with it.  At least I am learning heaps as I
