Can you extract a photo from a PowerPoint attachment

I get some nice powerpoint pictures of mother nature, all time great photos, etc from friends and family in their emails. Some are just beautiful, and I think I'd like to save them as a desktop photo, or just to store under my pictures, etc.
Is this possibe? If so-how does one go about doing that?

 

Oops, never mind

After I posted the above, I found the answer when "similar threads" became available under my post. I guess i should learn to formulate my search questions better.
