I need an experience PHP programmer to fix 3 bugs on a photo rating script. The fixes would not take too much time so please be reasonable on your bids. The following are the bugs that need to be fix: [url removed, login to view] one user can register one email address, No two user should have the same email address. Currently one email address can be entered as many times as the user wants for different accounts. [url removed, login to view] log out option needs to be fix. At this time is not functioning. [url removed, login to view] should not appear to the user more than once, unless the user had rated all pictures. Currently the photos appear randomly which is fine, but occasionally the photo already rated appears again right away. The live script can be seen at the following site: [url removed, login to view] I must see the script working without these 3 bugs before payment.
