Can someone walk a newbie through the steps to follow in order to remove a background color from an image? I have a png image loaded, but I can't for the life of me get rid of the background. Please be as cryptic as you like. Just list the tabs/selections I need to make to lose the background. Thanks in advance.

Please look at the software Help -> Tutorial -> Replace Image Backgeround menu and follow this tutorial.

To remove background you can use filter then go to extract. A window will pop up which will show you all the tools , then select a tool knows as draw an outline. Then with that you can draw a line to a portion which is needed by you. After doing this press ok , you will find an image without background.
