I am working on a site which has been upgraded from 7.2.8 to 7.4.3. There are a lot of images in the media library.

After the upgrade, a number of crops were added to the "Image Cropper" datatype. The crops appear when viewing the image in the media library but do not appear on the website until the image is saved in the media library. There are far too many images to manually save them to enable the crops.

I found this which seems to indicate that this issue has been fixed - http://issues.umbraco.org/issue/U4-7695 - but it doesn't seem to have been for this site!?

I have the following code:

var prevPost = new ArticulateRichText(prevItem);
var prevImage = prevPost.Image;

....
var imageUrl = prevImage.GetCropUrl("Featured");

But it doesn't work until the image has been (re)saved in the Media library.

The project uses ModelBuilder.
