README

Salted Herring's Cropper Field for SilverStripe. This is to avoid the deadly issue that FileSync task will disconnect all cropped images, when using silverstripe-cropperfield. Please remove silverstripe-cropperfield module if you have already installed it, other it will result in funny conflict.

2.0.0

Because in 1.x versions, cropping happens directly on the images, which makes them not available for "reuse", 2.0.0 is now to resolve this issue by redesigning the way that the cropper tool works.

Pleaes note: SaltedUploader will be retired soon. Please replace all SaltedUploader occurrences with CroppableImageField!!
