Plugin is getting old and using deprecated functions – should fix

First, is the author still supporting this plugin? Anyone knows?

It still works with WP 3.5.1 but the last update was in Sept 2011 …

The following crop up in the Admin Panel which can be fixed easily:

Notice: image_resize is <strong>deprecated</strong> since version 3.5! Use wp_get_image_editor() instead. in /home/<user>/public_html/web/wp-includes/functions.php on line 2839
