My gallery is gone!

I am having problems with my gallery. I uploaded 30 pics or so, some made it in, some didn't. I waited for a while for the other pics to show up, but they never did. And usually, when I went into my gallery It would not bring up any pics, only the descriptions. Now it says there are no pics in my gallery at all. Do I need to do it all over again??? Please say no...It wasnt easy prying my wife from the computer for an hour and a half!
