where'd they go

I was looking for some pics I attached to some old threads. The threads are there, but most pics are missing. They weren't uploaded using photobucket or any other on line album, soo...... where'd they go. Most noticeably the pics from the thread I posted on Jan. 29th, 2012, but many others have vanished also.
Is this thing working? I know it's the basement, but... I'm mostly just curious, but as luck would have it, I lost all copies of the pics from that date, went to retrieve them here, but no pics. Were they removed?
