Changeset 20806 for trunk/wp-admin/includes/image.php

Timestamp:

05/16/2012 05:47:55 PM (12 years ago)

Message:

Create a new attachment and make a copy of the image when selecting an image from the image library. This prevents orphaning the header if the original attachment is deleted. This also prevents stomping of meta.

Add a button to skip cropping.
