How do I find a picture on the Desktop, or in any form that appears on it?

I mean there is a picture anywhere on the desktop....
it always appears on another point and to random times.

I want that my program finds this picture anywhere on the desktop, or in a form on it and move the mouse cursor into the middle of the picture.

Does anybody know how to do this?

thx, sub-zero
