If you’ve been using WordPress for a little while, and don’t really much like the default options you have to choose from when a commenter doesn’t have their own Gravatar, why not make your own?

Make yourself a little square image to use that matches in with your theme, and then insert the following line of code:

<?php echo get_avatar( $comment, 86, 'http://example.com/custom-default-av.png' ); ?>

Note: you must provide the full absolute URL for your image.

What this line does, is show a Gravatar for the user if they have one, and if not, show your custom one instead. The number “86″ is the pixel width and height you want the Gravatars to display at.

Remember that this will only work in WordPress 2.7+, or possibly in older versions if you have the Gravatar plugin installed (not tested).

Update: If you don’t know what a Gravatar is, check out the comments. The avatar’s shown beside each comment are automatically pulled in from Gravatar’s service, so you upload your avatar once, and it appears everywhere when you comment etc. Get yourself one here: Gravatar
