Stacking 2 images together

[Guest]

I need to give credit for the graphics I use in my PPT presentation. I've
been told I can "stack" the images together. This means I would insert an
image and when I move my mouse over the image, the website for where I found
it appears. Essentially, I am placing 2 images back to back. How do I do
this? I have Powerpoint 2003.

How about a tool tip? See quick trick #16 at

Note that this won't work in the PPT Viewer, which might be a consideration.
