Get mouse position on single click, use screen coordinates to place an image file

If anyone has ideas about this I would greatly appreciate it. I am looking for a macro or some vba language that I can modify. A user is presented with an image in excel of an aerial view. On top of that image, I want to enable whereever they decide to click, another image will be placed on top of it (showing where certain events occurred; the user selects before hand what the event [and subsequently the image associated with it] will be).

When I have excel place the images, it does so whereever it decides. My preference is to have them placed by the user when they click the mouse, in the position where they have clicked.

Thank you!
