PicMonkey image editor

The integrated image editor could be easily replaced by the nicer and richest PicMonkey online tool. (http://www.picmonkey.com/)
PicMonkey is not limited to cropping and resizing. It's easy to add text (lot of integrated fonts), change colours, contrast, apply FX, borders, draw on the image, and so on.
With this tool, it's not necessary for you or your customer to upload/download pictures to fix or modify them. Everything can be done directly in the dashboard, simply click on the image in the file manager, and choose 'edit' in the menu.
