Would it be possible an inserted picture in a movie, shows a shadow?

Hello, a very simple question...
I normally insert pictures in my movies in VEGAS, and I don't know if would it be possible a simple JPG file, inserted in my movie (let's imagine I insert a little JPG picture and it is moving inside my movie form left to right ok?) would it be possible this picture show a shadow?
Editing text I have a lot of options, I can show a shadow, control the direction and color, outline the text etc. but with pictures, would this be possible?
Thanks
