Limit sigs to one image

[Andreas]

Almost the same modification as here:

In profile.php find

PHP Code:

if ($vboptions['maximages'] != 0) 


ABOVE that ADD

PHP Code:

if (fetch_character_count($signature, '[img') > 1)
{
    $preview = 'true';  
    $errors[] = 'Sorry, but you are not allowed to use more then 1 image in your signature';
}
