Yeah pictures are shown. I have seen this happen before with apps with no obvious fix, it was a real issue back in iPhone 3 but it does occur less and less now.
Weird things can happen when installing app updates normally but thats more rare. Upgrading iOS though has far more weird app issues after the change and I think thats whats happened to you.
Also people may think iOS doesnt need to be rebooted but it really REALLY does at least once a week or after a big batch of updates to minimise issues.
Yeah hopefully if it occurs with anyone else there's this thread in regards to it.
