I want to make picture cropping option for my website. Basically I have profile page. So people should have facility to upload their photos on the profile and make any picture their profile picture like facebook. We have only one standard size for the profile picture. If people will upload bigger or smaller size picture then they can use our cropping option to make picture proper . There should be a delete, rotate and make any picture as a profile picture options available in this section.
Profile picture changing facility on facebook is a good example.
