If you have the image in a backgroundless format such as  .png or .pspimage or .psd format, you can try right clicking the Eraser tool and going over where the background should be.  In Paint Shop Pro that will reveal whatever background that was there before it was removed. Doesn't work all the time, but sometimes it can reveal a credit.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
