Need .htaccess file help for image hosting site , hotlinking issue

my site is http://www.imagepundit.com

basically i want to allow hotlinking , but i want to block certain domains to hotlink. can this be done?

 

As you're already forcing all image requests through a script, it may be easier to add this in via PHP to the top of gallery.php rather than through .htaccess.

$from = empty($_SERVER['HTTP_REFERER']) ? false : $_SERVER['HTTP_REFERER'];
if ( $from ) {
    # Banlist
    $toBan = array();
    $toBan[] = 'domaintoblock.com';
    $toBan[] = 'another2block.com';
    $toBan[] = 'a3rdbannedone.com';
    # Extract domain from referer
    preg_match('@^https?://(www\.)?([^/]+)/@i',$from,$tmp);
    $domain = empty($tmp[2]) ? false : $tmp[2];
    unset($tmp);
    # Check domain against banlist
    if ( $domain && in_array($domain,$toBan) ) {
         header('Location: http://www.imagepundit.com/nohotlink.jpg');
         exit;
    }
}

PHP:

But if you want to use mod_rewrite, something like this should do (in imagepundit.com/.htaccess):

Options +FollowSymLinks
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_REFERER} domaintoblock.com [OR]
RewriteCond %{HTTP_REFERER} another2block.com [OR]
RewriteCond %{HTTP_REFERER} a3rdbannedone.com
RewriteRule gallery\.php nohotlink.jpg [L]

Code (markup):

Obviously duplicate the line that checks referrer and ensure all RewriteConds except the last have the [OR] flag.

Both untested but should be along those lines.

 

i just want the thing in the htaccess file , currently the file looks garbage

RewriteEngine on
RewriteCond %{REQUEST_URI} ^/images/thumbs/
RewriteRule ^.*$ - [L]
RewriteEngine on
RewriteCond %{HTTP_REFERER} !^http://www.imagepundit.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://www.imagepundit.com$ [NC]
RewriteCond %{HTTP_REFERER} !^http://www.imagepundit.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://www.imagepundit.com$ [NC]
RewriteRule .*\.(jpg|jpeg|gif|png|bmp)$ www.imagepundit.com [R,NC]

Code (markup):

i want a simple thing to allow hotlinking to everyone , but not to some websites , but i would like them to still see the thumbnail images hence
RewriteCond %{REQUEST_URI} ^/images/thumbs/

can someone clean it up for me , will give a footer link for a month on there if intrested
