Well all is not well with autolog. If I look at anything in my gallery it freezes. I can look at everything else though. Even if I just browse over the pics without opening them it freezes and the pics are just white boxes. Takes it a few seconds before it freezes.
I had the same happen a few nights ago, but it did not totally lock up, PS3 became unresponsive for a couple of minutes and then the pictures finally loaded.
Did you try to login to AutoLog using a web browser on computer and see if the gallery pictures are visible there?
