I received this in my inbox from an unnamed correspondant: "I've been sent this photo by several people in the past few days. Looks too perfect to be real."
(ETA: After comments, I've removed the image from the page, but you can view it here.)
Well, it's certainly been posted to the BridalBloopers website, but all the information with it states is that it has been posted by a woman named Amanda Sell from Mount Vernon, WA.
As to whether it's real or not, it's hard to say. The description on the website says: "If you can laugh after flashing 200 guests, you'll be able to handle anything in marriage right?" Of course, given the shot, it's impossible to tell whether or not this is a photograph from a real wedding or some sort of photo shoot, or whether the alleged 'flashing of 200 guests' occurred (isn't the bride usually facing away from the wedding party when throwing the bouquet?)
The photograph doesn't appear to be photoshopped, but the muscle structure and colouration of the bride's chest seem a little odd.
