XF 1.5 Lastpost avatar without extension

[Wyvh]

Greetings,
I'm trying to put a L-sized lastpost avatar on my forums, on the index, next to the lastpost infos, but I can't seem to do it.

I've tried the followings:

<img src="{xen:helper avatar, $user, l, 'true'}" alt="{$user.username}" height="96px" width="96px" itemprop="photo" />
<xen:avatar user="$user" size="l" />
<xen:avatar user="$forum.lastPost" size="l" />
<xen:avatar user="$user.lastPost" size="l" />
<xen:avatar user="$lastPost" size="l" />
<xen:avatar user="$category.lastPost" size="l" />

Any idea ?
Thanks.
