I can't help you with Photoshop.  But save your image as a .psd file so that you can work on it in Photoshop.  You can also save it as a .png file if you want a transparent 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
