How can I make a saved jpg, pdf, psd, etc., image "pop-up" when I move the
mouse cursor over the text within a cell in Excel? I know how to do the
hyperlink thing, but I don't want a "website" to open and I don't want to
click on the text. I've seen several websites with this feature. It's sort
of like a little help window. Is it possible to do it in Excel? Using
Microsoft Office SE 2003.
