IPhone photo album is frozen?

I tried to attach a video through my photo album to an email. It said it was too long and to try to shorten it… So I cut it in half. It then said "preparing video".It's been stuck on 50% for 14 hours and now I can't take any pictures or even view my pictures because my photo album is froze in the "preparing video" stage. How can I fix this?

Try to delete the video. If that doesn't work call 1 800 my apple for tech support.
