Ok everyone, I finally had a chance to get some more pics taken. I have uploaded these to the same photobucket link. I also too some measurements of everything. They are as follows.
Headboard overall width - 55-3/4", inside - 52-3/8", sideboard flange to inside of headboard - 1"
Height - 85" see pic
Footboard overall width - same as headboard, sideboard flange to inside of footboard - 2-3/4"
Height - 37" see pic
Sideboard overall length - 73-5/8"
So it looks like it will fit a mattress up to 52" x 72"
Thanks everyone for the input.
