Wordpress avatar url

/ Published in: PHP

I pinched the get_avatar() function from the wp/wp-includes/pluggable.php file and commented out the setting of the avatar as an tag and returned the actual image url instead.

Copy this code and paste it in your HTML

function get_avatar_url($id_or_email, $size = '96', $default = '', $alt = false) {
	if (! get_option('show_avatars')) {	return false; }
 
	if (false === $alt) { $safe_alt = ''; }
	else { $safe_alt = esc_attr($alt); }
 
	if (!is_numeric($size)) { $size = '96'; }

	if (is_numeric($id_or_email)) {
		$id = (int) $id_or_email;
		$user = get_userdata($id);
		if ($user) { $email = $user->user_email; }
	}
 
	elseif (is_object($id_or_email)) {
		// No avatar for pingbacks or trackbacks
		$allowed_comment_types = apply_filters('get_avatar_comment_types', array( 'comment'));
