Show avatar on non-vb Pages

[skariko]

Hello,
i trying to display the avatar on an external page from VBulletin.
I try this code:

<a style="padding: 0" href="http://www.czeta.it/forum/profile.php?do=editavatar"><img src="<?php echo get_option('vbb_VBURL') ?>/image.php?u=<?php echo $vbulletin->userinfo['userid'] ?>&ampampamp;dateline=<?php echo TIMENOW ?>" alt="<?php echo $reply['username'] ?>'s Avatar" class="avatar avatar-32 photo avatar-default" width="50" height="50" /></a>

and it works. But only if the user use an custom avatar.
If the user use a 'basic' avatar it doesn't go.

How can i show always the avatar?
