IMPORTANT: person who takes this job must be able to create an installation guide that contains all changes for me which looks similar to this format:
Find/Before/After (<-pick one only):
Add/Replace (<-pick one only):
1. The bug happens when I rate a photo and it moves to next photo. If I push back button on browser, I can rate the photo again because it doesn't update my vote when I push back button. This happens to guest and users who vote. I need this fixed.
2. The other bug is when a user opens multiple windows of the photo, he can vote the photo multiple times. So there needs to be a way to only vote 1 for guest and users. (IP tracking for guests).
Person who does a good job will be hired again.
