Here's your President Obama conspiracy theory for the day: Was he Photoshopped into the iconic image of the Situation Room meeting during the Osama Bin Laden raid? No, probably not. Nevertheless, a post by Mara Zebest—" a graphic artist and co-author for a number of Adobe product books, including the Inside Photoshop series," per her bio— on the conservative American Thinker argues that he might be, basing the claim mostly on the apparent size of his head:

Compare the size of surrounding heads in the "Situation Room" photo to the size of Obama's head.  Even if you use a perspective argument -- in which objects appear smaller at a greater distance -- then why are the faces behind Obama still larger?

Maybe they have large faces? It's worth noting, of course, that the post's author Mara Zebest has used similar analysis to "prove" the president's birth certificate is a fake. Her argument didn't convince us, or many others. Bloomberg's Joshua Green tweets, "the new birtherism." "Birtheresque!" says Reuters' Jack Shafer. Our objections aren't so much technical as they are logical. Why would the White House Photoshop this particular photo in this way? If you were the White House, and you had a blank Photoshop slate from which to start, wouldn't you do something even more triumphant? Like, perhaps, Obama's fist pounding a giant red "KILL" button on his Oval Office desk or something? But hey, not everyone's so skeptical. The post piqued the interest of famed cleanser of the Romney staff Bryan Fischer. So there's that.
