Is this why they call it the White House now?
First, a disclaimer: 4chan is well known to be an unreliable information source. Be that as it may, if this is a hoax, someone did their homework. I haven't found anything to indicate it is a fraud yet (not that I'm an expert either.).
Matt Rooney at The Save Jersey Blog found an image uploaded there that could be quite damaging to the White House. If the data he claims to have gleaned from the image is true and accurate, it would appear that someone, using an iPhone took a photo on 01/11/2010 at 18:05:47 local time facing southwest, of what appears to be three lines of a white powder, perhaps cocaine, on a desk or tabletop, along with a double edged razor blade and a glass of red wine or perhaps brandy. The iPhone camera recorded the phone's location, orientation and altitude from the phone's built in GPS and stored it as EXIF metadata in the image. The location, if true would put it on the residence level, approximately in the west room between the president's cosmetology room and the north hallway. Unfortunately it cannot be pinned down precisely by us mere mortals because we do not know what the intentional error being broadcast by the GPS constellation at that moment in time was. The original image link is not longer valid, it has been taken down it would appear. I wonder if there might be a way to tie the SN or IMEI # of the iPhone to the image. If so we should be able to get down to the owner of said phone. It would presumably belong to the person that took the picture.
Maybe Larry Sinclair wasn't such a nutcase after all....
