This is a simplified version of our free WordPress plugin - LoftLoader. And, a few hours ago I just found that someone has stolen it, changed the name, and started to sell. The guy stole everything, even the description content written by me. This is ridiculous because we were meant to share it for free. Anyway, I have submitted a support ticket to Envato.
If you are a WordPress user, you can download and play with LoftLoader: https://wordpress.org/plugins/loftloader/
Yes, I am still kind of angry.
