I get no image errors
The errors on your page are do to the fact that when you altered everything per the
VB FAQ on relative paths you left out a step
Your error comes from line 1244 of your code which is your
VB footer
// Main vBulletin Javascript Initialization
vBulletin_init();
It is caused because in your header include template you have not altered the relative paths for the java script. That can easily be seen by viewing the source of your page
<script type="text/javascript" src="clientscript/vbulletin_global.
js"></script>
<script type="text/javascript" src="clientscript/vbulletin_menu.
js"></script></head>
Alter that in your template file I meantioned and your java error will go away
