What does the piece of paper icon mean after I edit in Photoshop CS5.1 then go into bridge and it shows the original picture and the paper next to it?

after editing a picture in photoshop cs5.1, I go back into Bridge and the original photo is there but the edited version in an icon of a piece of paper with the edge lifted up. What does that mean? And then when I click on it i get a box that asks how I would like to open the file. I just want the edited picture to show up like it used to. I shot with a Canon 5d Mark III in JPEG format. Thank you for any help.
