Hello,

The plugin is excellent. Could you consider adding a filter for the “image” meta name instead of hard-coding it?

It would be great if it had a filter, perhaps something like this

$image_field            = apply_filters( 'og_term_thumbnail_meta', 'image', $obj );
$image_id                = intval( get_term_meta( $obj->term_id, $image_field, true ) );

Thanks.
