President Obama made the right choice, in my opinion.
The community needs to be able to put some trust in the president. Some trust in all of the countries and even Al Qaeda saying that he is, indeed, dead.
If people don't believe he's dead, they wouldn't be satisfied with pictures, either. Take birthers, for instance - they insisted on seeing Obama's birth certificate. They weren't satisfied with the fact that in order to get a job or a passport or a driver's license or any other number of things that he'd have to have shown his birth certificate to other people. When it was released to the public, they still weren't satisfied.
People would just cry that the images were photoshopped or that it wasn't really bin Laden or whatever. Conspiracy theorists are never satisfied.
