Easy whatever you have going on in
VB is not valid html without knowing what html you have altered I cant say but just looking at this from the source of your photopost
<table width="100%" border="0" cellpadding="0" cellspacing="0" width="100%"><td>
<table width="100%" border="0" cellpadding="0" cellspacing="0" background="/forums/images/FunMac/misc/bannerbg.jpg">
<tr>
<td height="74"><table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td rowspan="2"><a href="/forums/index.php"><img src="/forums/images/FunMac/misc/logo.jpg" width="224" height="74" border="0"></a></td>
SEE THE MISSING TABLE TAG BETWEEN THE TD AND THE TR ABOVE. This will definately cause this.
