OK, my comments loop is handled by functions.php, and i have avatars set at 32:
<?php echo get_avatar($comment,$size='32',$default='<path_to_url>' ); ?>
What i'd like to try and figure out is how to make a parent avatar 32px, but make children 16px.
There must be a way to do this, i do not know php at all really, but an idea along this line should maybe work, just i don't know how to code :)
if parent echo get_avatar($comment,$size='32',$default='<path_to_url>'
else
echo get_avatar($comment,$size='16',$default='<path_to_url>'
