My take: I tend to agree with those who think that the decision to withhold the photos was taken so the photos wouldn't crap all over
Obama's upcoming speech in Cairo, the goal of which reportedly is to reassure Muslims we're not at war with them. (Never mind that we're occupying 2 Muslim countries, imprisoning hundreds, and killing Muslim civilians, women and children...)
I think there was a failure to anticipate how much this would action would be perceived as a torture-enabling cover-up.
