I had problems with snapshots taken downtown and at uni not showing up in the neighborhoods\N00#\Storytelling folders, too, and then a few days ago I found that those pictures had somehow ended up in the EA Games\The Sims 2\Storytelling folder. (I think that's the folder the pictures were stored in before Uni?) All I had to do was move them to the "normal" storytelling folder and they showed up just fine in game.
