Item frames with items disappear

I have a storage area that I created with 104 trunks. each one had an Item frame on the left side of the trunk with the item that was stored in that truck on it. I went to that storage area and all the item frames with items had disappeared, or in this case became invisible. The graphics for item frames will not load. I hit and broke the block that the item frame with item was on and collected them into my inventory, but when I tried to put the block and item frame back, it still does not show up. I have explained this as clearly as I can. please send a patch to fix this. I have no attachements to include with this report.
