Allow hotlinking for thumbnails?

[AvrilBoi]

Hi!
I have put a .htaccess file in my /albums/ folder, to prevent hotlinking.
This is the code:

Code Select Expand

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?allowed_site_1.com [NC]
RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?allowed_site_2.com [NC]
RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?allowed_site_3.com [NC]
RewriteRule \.(jpg|jpeg|png|gif|bmp)$ http://www.alternative_server.com/hotlink.gif [NC,R,L]

Is there any way to allow people to hotlink thumbnails? My thumbnails are named by coppermine default: "thumb_filename.jpg"
Thanks

It doesn't seem possible unless you use a different file extension for thumbs. For example, if you use .jpeg for thumbnails and erase jpeg from the list of protected files types.

This would require making changes to the Coppermine code, so I wouldn't really recommend it. Perhaps someone could propose a better idea.

There's no easy solution: you either allow hotlinking or you disallow it. You can't come up with a determination that hotlinking of thumbs is allowed, but intermediate/fullsize hotlinking is forbidden.
As Thu suggested: it would require extreme hacking to accomplish this.

Ok thanks...
I've asked that because I've read something like this

Code Select Expand

RewriteCond %{REQUEST_FILENAME} !(.*thumb|.*highlight) [NC]
somewhere else so I thought that would be possible.

Sorry for this double post, but I just figured out that that code works!

Code Select Expand

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !(.*thumb|.*highlight) [NC]
RewriteCond %{HTTP_REFERER} !^$
etc. etc.

Interesting. Thanks for coming back and posting the solution.
