"extract"

just wondering how i go about extracting a backround from an image......found this tutorial site that explained it, but when i went to do it it told me go to like
image->extract->options
or something along those lines i do know it was image->extract
not sure what or if, anything came after it....
anyways needless to say when i went to Image i found no "extract" option to use.....
I am running photo shop 7, and need to know how to do this
any help people? hit me on yahoo msngr if u have it
