Thanks for this tutorial! When I put the code in my custom_functions.php, I get this message where I should normally select my image as the custom default:

Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘fb_addgravatar’ was given in /home/simplem4/public_html/wp-includes/plugin.php on line 166

Warning: Invalid argument supplied for foreach() in /home/simplem4/public_html/wp-admin/options-discussion.php on line 202

Any ideas why? Thanks so much in advance.

Okay, so I retyped all of the quotes to make them un-smart quotes, but them in code tags, and yet they turned ’smart’ … that’s too smart for me.

Heck, even in the code I entered in my last comment above you'll see that smart quotes snuck in there! I'll try one more time:

/* Add a Custom Default Gravatar */
if ( !function_exists('custom_gravatar') ) {
function custom_gravatar( $avatar_defaults ) {
$myavatar = get_bloginfo('template_directory') . '/custom/images/visitor-avatar.gif';
$avatar_defaults[$myavatar] = 'visitor';

return $avatar_defaults;
}
add_filter( 'avatar_defaults', 'custom_gravatar' );
}

Ah, found what the issue was for me. The code above had smart quotes and my text editor didn’t strip that out for some reason. Also, I had to change ‘fb_addgravatar’ to ‘custom_gravatar’ since that appears to be the function being declared in the first part of the code.

/* Add a Custom Default Gravatar */ if ( !function_exists('custom_gravatar') ) { function custom_gravatar( $avatar_defaults ) { $myavatar = get_bloginfo('template_directory') . '/custom/images/visitor-avatar.gif'; $avatar_defaults[$myavatar] = 'visitor';

return $avatar_defaults; } add_filter( 'avatar_defaults', 'custom_gravatar' ); }

Now it works great! I was able to find my cute little custom avatar in WordPress Settings – Discussion – Avatars – Default Avatars. Thanks!

Hey Rae, I’ve picked up quite a few tips from you over on sugarrae.com. This looks like a great one, too!
However, I’m a bit befuddled as to why it isn’t working for me. I’ve copied in your code into my custom_functions.php file, changing the image name (visitor-avatar.gif) and the name I’ve given it for the Discussion menu (visitor) and yet I don’t see it there in WP. Any ideas? (Site: thegreenthree.com)
Thanks!

Oh, the coding seemed to be confusing to me..
I am not so good in dealing with codes.
I am always upset when I see coding works….
But Anyways thanks for sharing the tutorial…

@jlbraaten: Gravatars for Drupal is really easy. http://drupal.org/project/gravatar

Awesome Tut.
How would you go about creating a set or a few generic Gravatars to be selected at random, like Identicon (Generated) and others’ that have a few in their set? Or is that beyond the scope of this method?
