Accurate cropping

Many users are working in a CMS and have a custom format for their images. For example, images on a site all have 500 pixel width. In Online Image Editor you simply crop an area of the image down (or up) to 500 px width. You can do this with the manual crop option. You get a dotted rectangle that you can drag over the image and also change in size. In the status bar you will see the exact dimensions of the crop rectangle. You can also add to the script that calls Online Image Editor the CropWidth and CropHeight and limit the crop function to exactly those dimensions.
