I guess you don't need to believe the pictures. I understand what you mean, but your concern is exagerated.
I agree, they have been generally accurate, but most of the time they tend to sensationalize and exagerate their stories pretty intensely.
The pictures do help to corraborate the story and while I do believe it is true, I just find it odd that it hadn't been picked up anywhere else. (though reports are starting to surface from other sources)
