Imagefield Crop gives us four elements in the editform:
The preview image (preview)
The small image where you do the cropping (cropbox)
A link to the original image (file)
A remove button

The bug?
The link to the original image links to the cropped version instead of the original image.
You can get the original image by right clicking on the cropped preview image.

Still, the link should point to the origianal file. Line 318 needs some work, I think (haven't got the time to test just now)
