So you’ve just finished upgrading, everything went smooth and you now have some time to amend the core of WordPress to accommodate for the hacks and workarounds you have implemented over the time. You have styled, laid out and customised your comments, you have changed the default size of Gravatar, Avatar or any other user pictures you display only to find them going back to default (32px × 32px) as soon as you upgrade.

Worry not! In order to change it back to what it was, head to: “wp-includes/comment-template”, locate line #1322 (function wp_list_comments()) and change the defaults array value (“avatar_size”) from 32 to anything you like (we use 50px), so the result will read:

$defaults = array('walker' => null, 'max_depth' => '', 'style' => 'ul', 'callback' => null, 'end-callback' => null, 'type' => 'all',
'page' => '', 'per_page' => '', 'avatar_size' => 50, 'reverse_top_level' => null, 'reverse_children' => '');

And zet is zit. Save and refresh your comments page and enjoy, your user icons and images are exactly big (or small) as intended.
