Did iOS7.1 just corrupted my pictures?

Hi all,

I recently upgraded my iPhone 5 from 7.0.6 to 7.1. It's been great so far, until I opened my camera roll pictures, and saw this:


Almost all my pictures and videos are showing the icon only, except for the most recents pictures I took.

I tried to backup and restore from iTunes twice but no luck. And it also does the same to my Photo Stream as well.

Does anyone else have experienced something like this before? Do you guys have any solution to this?
