Hi Bill,
Using Event.PointerX() and Event.PointerY() you can get the
absolute
position of the mouse on the page.
Using Element.Layout you can get the exact position of your image.
If you substract the layout's left value to PointerX and the
layout's
top value to PointerY, you should have the X/Y position relative to
top/left corner of your image.
More simple but I am not sure it is crossbrowser supported, events
*may* have clientX and clientY attributes which *may* contain what
you're looking at (if your event is attached to the img DOM
object).
Take a look at Element.cumulativeScrollOffset and see if that can
give you what you need. According to the docs, it can handle
multiply-nested scrolling containers.

I looked at that, but I do not want to account for the scroll of the
body, and cumulativeScrollOffset seems as it would do that.
I need the scroll of the div contents only.
You can back into that by using the cumulative offset, and subtracting
the document.viewport.getScrollOffsets() from that.
Walter
Thanks for the thought

I can use clientX/Y or pageX/Y to get the location of the mouse,
but I can't figure out how to get the scroll of the _DIV_.
I looked at the options available for Element, but which will give
me the amount that the contents of the _DIV_ have scrolled.
pageX/Y gives me the amount the body is scrolled, not the _DIV_.
