Graphics not showing for unregistered users

[anarchystar]

I have been having a rather odd problem with my site ... whenever a unregistered visiter hits my site, www.anarchystar.com, none of my graphics will dispaly on the index page. I am using VBA with the forums at a sub-domain.
Once users log in, all the graphics appear, except the ones in the images/icons/ folder

The really strange part is that the problem is only a problem in IE, everything works fine in Firefox.

I think this may be related to some code I put in my .htaccess file to stop people from linking to pictures in my gallery:

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www\.)?anarchystar.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://(forums\.)?anarchystar.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://(gallery\.)?anarchystar.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://(www\.)?google\. [NC] 
RewriteCond %{HTTP_REFERER} !^http://(www\.)?search\?q=cache [NC]
RewriteCond %{HTTP_REFERER} !^http://(www\.)?yahoo\. [NC]
RewriteRule \.(gif|jpg)$ - [F]

Now, as for that icon folder, no graphics will show up from that folder in IE or Firefox. It is just less noticable in Firefox due to the lack of huge red X's the IE has.

anyone got any ideas on what the issue could be?

I have narrow this down to a permissions problem on my site. I have not been able to find a permission that would cause this problem though. Anyone got any idea?
