Hey Guys,
I am a newbie in the field of web development and designing. I have been doing some work recently on a custom website of mine just for interest sake, have been gathering new ideas from a whole lot of websites. While I was browsing the net, i came across this website http://www.zomato.com . For registered users, they have implemented a cool photo cropping feature on personal profile for a user, using which the user can crop any photo once he uploads it. Can someone please give me an idea as to how this photo cropping works, and how to implement it?
