We've all been there. You have an image which is too big to fit on the website, and it needs to be resized or cropped. Resizing can make your image look bad in quality, because of the pixels getting merged. This can make things impossible to see, and your image is damaged. Cropping on the other hand, removes the pixels completely, and sometimes you just don't want to remove things from an image - sometimes you need the entire content of the image.

Your solution is here. I found it at Channel 8 and there is a Youtube video referenced, where you can watch the algorith in action. It even enables you to enlarge an image beyond it's original size without dropping in quality. That is so cool.
