Glad you like the Image Crop Tool. It is our own development and works similarly to the link you sent, but it has a Flash front-end (to create all the settings) with a php back-end (to resize the image, backup a hires version and write the images into the Oracle DB etc). In addition to cropping you can also resize the image, even blow it up if it is too small (will be sharpened if necessary), move it around and when you have finished editing it, the image is written back into the HTML code with the right CSS classes applied to it using JS.
You can even go back to your article and then re-edit the image at any time if it still needs changing after you have published it. Altogether it is a quite adventurous approach, but it works very well on all systems/browsers. It is a very useful app which I hope will benefit a lot of people. It actually makes cropping and resizing fun!
We’ll be posting a how to guide and demo video when we launch the new tool – so you can see more then.
