I placed my original post sometime ago.

I really never got much of a response to it. I guess the group never
really felt it was much of a topic that needed discussion.

I just completed a project that had this very issue as one of our
sticking points.

So, I am replying to Carl (I don't have any record of my originally
replying, sorry Carl) here hoping that after some time this might
initiate some responses.

Walter

Well, isn't having an Image fire off the submit command of a Web form,
in practice the same thing as the Image being a Submit Button?

Or are we splitting hairs here?

Or maybe I should have said: "you can use an Image in place of a
Submit Button."

What I should have said here...

   These are the coordinates where the mouse hit *a* graphic. But we
don't know
   Which graphic was hit and I think that this is important.

I really don't think that is what I was saying.

I am just looking a way to enhance the current syntax to include
additional information without breaking existing programs.

This solution tells us which image was hit *and* where it was hit.
A very nice and neat little package.

And again, I really hope to hear some discussion on this topic.
