The plugin is disabled for the admin panel and will only function for the front end. If you feel like manually editing the plugin open up user-photo.php and find the following function.
function userphoto__init(){
if(get_option('userphoto_override_avatar') && !is_admin())
add_filter('get_avatar', 'userphoto_filter_get_avatar', 10, 4);
}
Simply just remove the && !is_admin()
from this function and the ‘Override Avatar with User Photo’ will work within the admin & front-end.
Just in case you’re feeling lazy:
function userphoto__init(){
if(get_option('userphoto_override_avatar'))
add_filter('get_avatar', 'userphoto_filter_get_avatar', 10, 4);
}
Be warned when editing plugins as an update could revert your changes, the author should really make this another option in the admin panel!
