Fix facebook app + create script to create apps faster and manage them

This project is divided into two but related to each other. 1. Fix my app. I currently have a quiz app that is supposed to post a photo to the user. Now, I encounter this error: fatal error: call to undefined function imagecreatefromjpeg.. I need you to fix it and make my app functioning. I think this one is easy to fix and I kinda know what file needs to be edited to fix this but i just dont know how. 2. Create a script where I can create apps faster and manage them as well. I actually want to create 50 duplicates of the same app that I have. I dont want to manually copy paste and edit files in my cpanel to do this. So, I want to have some sort of script to do this faster. I'd also like to be able to manage my apps by knowing how many users are in each app. Also, I'd like to be able to set a limit on how many users are allowed to be on the app. Once the app reaches the limit, the next users will be redirected to the next app and so on and on. Not sure how you will do this but I have a sample script which maybe similar (though it's not functioning).. here are images: 1. Managing the app: [login to view URL] 2. Creating an app: [login to view URL] I want to have something similar to that... where I just need to put the details in the form and it will create the app.. I can send you the sample script and I also have a demo of it, but not sure if it's working. My budget is only 150$ - 250$
