You can also save the image as a .png or a .tiff file and apply the image to itself as a mask in your graphic program. That will get rid of the background too. Remember the delete the mask layer though so you can work on the original image minus the background.

"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
