Kroppr: image cropping script
Kroppr is an unobtrusive script that will enhance any site that wants to offer an image cropping tool for its visitors.
Unlike other scripts, Kroppr is able to ROTATE, zoom and move the image in the real time without using plugins – such as flash or java. The cropping is done after the user is satisfied with the settings. This way, the load put on the server is minimised and also the visitor’s experience.
The installation is also very simple – add a script tag in the header’s page and a class to the image that must be cropped.
