Changeset 48905 for trunk/src/wp-admin/includes/image.php

Timestamp:

Message:

Media: Make the is_gd_image() function available on front end.

This avoids a fatal error if a plugin calls image creation or editing functions like wp_imagecreatetruecolor() outside of the admin.

Follow-up to [48798]

Props BackuPs.
Fixes #51174. See #50833.
