Picture/Photo Shop. Help.

Hi, i have a picture of myself. and it has a logo on the bottom and i wanted to get rid of it. but i dont want to like clean the whole thing.. like on paint, where you 'clear section' i dont want that. i just wanted to get rid of the logo on the picture. the logo is right in front of my shirt. and i wanted to see the whole shirt and not just the logo plus the shirt. sorry if i am confusing you guys. just wanted to get rid of the logo which says. "CAM WOW" for the iphone.
