555613 Decipher PHP Quiz Script and Fix Bug

I purchased a PHP Quiz Script a few years back and am trying to bring it up live today. It apparently has Facebook integration where you can play the script within a Facebook framed window. Also, there's a bug when you attempt to create a quiz, you are forced to include a photo to proceed. The ask here is two fold 1. Demonstrate how Facebook integration works. I want to see it working live and document what needs to be done on my end to setup multiple quizzes in FB 2. Fix the bug where creating a quiz will not always require that an image be included. It should be optional If you're looking for quick work and are a PHP expert, this is the project for you. Do a great job and get some bonus recommendation points added to your account. This is a tiny job for the PHP professional. Ask here is to fix a tiny bug and document how can I use the FB integration. Of course, you must host the app on your box so I can see it. Good luck. The script is attached. Have fun!
