I can't see the photos either, but if anybody wants to borrow them and post them here I could probably be more specific.
Thin steel is the biggest weakness of gun safes. You can generate thousands of pounds of pressure if you know how to use a pry bar. Any steel measured in gauge is susceptible to a basic pry attack. Thicker steel is definately better, but I have seen B rate safes pried open, and those are usually 1/4" bodies with 1/2" doors.
Edited to add:
I was able to see the photos, and the door and door frame held up better than would have expected. That is a good sign that the boltwork in that paricular model is much too weak. Given enough pressure, any short bolts like that will twist, but that pressure should be great enough to deform the door or its frame.
