We do not autotranslate header image paths if they are not the normal
VB path as in your example afterdark.
You would need to change those relative image tags to full url to work overtop of Photopost
As far as avatars what your forum url set to? we use the forum path
if ( $hasav ) {
if ( isset($avpath) )
$userprofile[6] = "<img src=\"{$Globals['vbulletin']}/$avpath\" border=\"0\">"; // Avatar
elseif ( $vboptions['usefileavatar'] )
$userprofile[6] = "<img src=\"{$Globals['vbulletin']}/$vboptions[avatarurl]/avatar{$cuserid}_{$avrev}.gif\" border=\"0\">"; // Avatar
else
$userprofile[6] = "<img src=\"{$Globals['vbulletin']}/image.php?u=$cuserid\" border=\"0\">"; // Avatar
}
