Changed the avatar upload_to path to not rely on the user supplied name, as this has caused problems in the past (too long). Now just store avatars under media/avatars/users/username.ext.

<div class="smiley_farm">
{% for s in smilies %}
<img src="{{ s.image.url }}" alt="{{ s.code }}" title="{{ s.title }} {{ s.code }}" />
{% endfor %}
</div>
