Hello Sir,
It's Prabir. I have 9 years experience in PHP and designing and developing the Facebook application since 2008. I have expertise in Facebook Graph API version 2.3
We have developed more than 150+ Facebook applications till now successfully. To clarify, please check our reviews here https://www.freelancer.com/u/innovera.html and here [login to view URL]
As you specified in project details, we have developed similar type of Facebook applications where user can edit profile/cover photo. Please check app links :
1. [login to view URL]
2. [login to view URL]
3. [login to view URL] (click on any cover photo)
This will be the flow of the application as per my understanding. Please correct me if i am wrong.
1. First let me know how you want to showcase the app in Facebook as a Page tab application ([login to view URL] name ) or as a canvas application ([login to view URL] name)
2. We ask user to allow the applications.
3. When user allow it, we will automatically retrieve their name, email address etc.
4. We also retrieve their profile picture followed by automatic overlay addition.
5. User review it and set as their profile photo and share it on FB wall.
7. Provide you an user friendly ADMIN panel to change or add other overlay colors or images.
Please get back to me and let me know if you have any query about above points.
Thanks,
Prabir
