Prevent hotlinking [not working]

[Chirrilona]

I set this code fore my site, but I have problems. I cant see pics in my gallery.  So the code is working, but in wrong way. I put .htaccess in my album folder.
How I must set it up, cos I have installed gallery in this way -> mysite.com/gallery

SetEnvIfNoCase Referer "^http://www.mysite.net/" locally_linked=1
SetEnvIfNoCase Referer "^http://mysite.net/" locally_linked=1
SetEnvIf Referer "^$" locally_linked=1
<FilesMatch "\.(gif|png|jpe?g)$">
  Order Allow,Deny
  Allow from env=locally_linked
</FilesMatch>

Post a link to your gallery and the actual .htaccess file (not the one with dummy placeholders).

Here is my file and link www.telenovele-slo.net/galerija

RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www\.)?telenovele-slo.net/galerija(/)?.*$     [NC]
RewriteRule .*\.(gif|jpg|jpeg|bmp|png)$ http://telenovele-slo.net/nolinking.jpg [R,NC]

RewriteRule .*\.(gif|jpg|jpeg|bmp)$ http://telenovele-slo.net/nolinking.jpg [R,NC]should do the trick. However, when entering the URL of one of your pics manually (e.g. http://www.telenovele-slo.net/galerija/albums/userpics/zharick%D7.jpg), I get

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, telenoveleslo@yahoo.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

, which indicates that there is something fishy with your webserver setup. Make sure that you're actually allowed to use mod_rewrite. Contact your webhost for details.

I asked my webhost and they said I have permission. So what else could be wrong? 

[Joachim Müller]

That's nonsense. When accessing a jpeg file, the server mustn't return a 500 internal server error. If it does, there's definitely something fishy with the server's setup. When going to http://www.telenovele-slo.net/galerija/albums/userpics/ or http://www.telenovele-slo.net/galerija/albums/userpics/foo/bar/whatever.jpg (a file that doesn't even exist) I get a 500 error as well. Tell them that they need to fix this - you're welcome to refer to this thread. Refering to a non-existant file should result in a 404, but definitely not in a 500.

They said thats how works their rewrite [look code below].

cat .htaccess

[Joachim Müller]

How is that suppossed to be related? There are no files named "property.php" nor "tag.php" in Coppermine. Hotlinkink protection needs to take care of the contents (images), not some PHP files.
However, if this is what your webhost recommends to implement, then ask them for support if it doesn't work.

I have put an .htaccess in albums folder which looks like this

# Second condition: the referrer must not be blank.
# This means that people who aren't passing referrer headers, for whatever reason,

Chirrilona u r getting the 500 internal server error because u r preventing the jpg from being hot linked and finally redirecting the user to a jpg file it self. see the code below

RewriteRule .*\.(gif|jpg|jpeg|bmp)$ http://telenovele-slo.net/nolinking.jpg [R,NC]

here what u need to do is create a png file ( nolinking.png ) and redirect the user to that file upon hotlinking. hers the correct code

RewriteRule .*\.(gif|jpg|jpeg|bmp)$ http://telenovele-slo.net/nolinking.png [R,NC]
