Trying to display senders avatar

[Dave Strider]

I have the following code and it somewhat works:

				if ($vbulletin->userinfo['userid']) {
					require_once(DIR . '/includes/functions_user.php');
					$userid = $pm['fromuserid'];
					$pmavatar = fetch_avatar_url($userid);
					if (!$pmavatar) {
					  $pmavatar = $stylevar['imgdir_misc'] . '/unknown.gif';
					}
					else {
					  $pmavatar = $vbulletin->options['bburl'] . '/' . $pmavatar[0];
					}
				} 
				else {
				  $pmavatar = $vbulletin->options['bburl'] . '/image.php?u='.$userid.'&type=thumb';
				}

however the output is the following:


The second avatar in the image should be in the first space while the third avatar should be in the second and third space as it's from the same user. I feel like I'm on the right track just don't know where to go from here, can anyone help?
