Answer 1

If @Ryan answer (marked as solution) does'nt work for you, try to change

add_filter('get_avatar','add_gravatar_class');

function add_gravatar_class($class) {
    $class = str_replace("class='avatar", "class='avatar pic-2", $class);
    return $class;
}

into

add_filter('get_avatar','add_gravatar_class');

function add_gravatar_class($class) {
    $class = str_replace('class="avatar', 'class="avatar pic-2', $class);
    return $class;
}

This start's work for me after replace " with '.

Check out the WordPress Codex for more info:

http://codex.wordpress.org/Using_Gravatars

For the size, try wrapping the second parameter like so:

<?php echo get_avatar( get_the_author_meta('ID'), $size = '96' ); ?>

The default html output is like so:

<img alt='' src='http://gravatarurl_or_default' class='avatar avatar-$size' height='$size' width='$size' />

You can style the default class 'avatar' in place of 'pic-2'. If you still want to add a class , you can do it via javascript like so:

$("img[class='avatar']").addClass("pic-2");

Hope this helps! : )

Another way to do this for future searchers, very simple string manipulation which is probably a bit safer if they change the function in the future e.g. it'll likely always have a 'class'.

    $grvimg = get_avatar('email address', 200);
    $grvimg = explode("class='", $grvimg);
    $grvimg[1] = 'your-class ' . $grvimg[1];
    $grvimg = $grvimg[0] . $grvimg[1];
    echo $grvimg;

I think the best way to handle this would be to use a filter, rather than using jQuery as George suggests. You would simply add this to your theme's functions.php file.

add_filter('get_avatar','add_gravatar_class');

function add_gravatar_class($class) {
    $class = str_replace("class='avatar", "class='avatar pic-2", $class);
    return $class;
}

*Note, I've not tested this, but believe it will work. See this thread for more info.
