Changeset 20384 for trunk/wp-admin/custom-header.php

Timestamp:

Message:

Make choosing a header image from the media library play nicely with file replication plugins that do not guarantee images will be retained in the local filesystem.

• When passing an attachment ID to wp_crop_image(), use load_image_to_edit() to fetch the image via a url fopen when the image does not exist in the filesystem.
• Move load_image_to_edit() to wp-admin/includes/image.php so that it is always available for admin pages loads.
• Fallback to the height and width stored in the attachment meta when the image no longer exists in the filesystem.

see #19840
