SRC = "name_of_image.jpg?43234324"

If this number changes, then the old image won’t be pulled from cache. For my cgi generated pages this is easy enough. For my more-or-less static pages, I changed them to shtml, and then do an include on a text file that is nothing but an hourly changed random number. I imagine that other ways of working would have methods to do the same.

One slight problem that was driving me crazy yesterday: Browsers that allow you to configure them such that they send no HTTP_REFERER variable will always bypass hotlinking protection.

I believe you can also put it inside the WP rule as in:

# BEGIN WordPress

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www\\.)?yoursite\\.com [NC]
RewriteRule .*.(gif|jpe?g|png|bmp)$ [F,NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

# END WordPress

but I’ve not used this method, and as a suggestion to others I wouldn’t use ‘http’ urls inside the htaccess file for directing to an ‘hotlinking’ image, use the path method as used by author ‘/images/hotlink.$1′

Unfortunately it will display from their cache but try changing the name of the image.

@ Jogos (24)

I think you only need to add ’swf’ to the ‘RewriteRule’ and not the path to the file(s):
ie: RewriteRule \\.(gif|jpe?g|swf)$

@ nasir (22)

Maybe specify ‘jpg’ in the Rewrite Rule and have your thumbs as ‘jpeg’ ?

@ Manuel (13)

Yes it does break images for RSS feeds but there are workarounds depending on your platform.

ie: In Wordpress there is a hotlinking plugin that stores the RSS images in a different folder and uses them for the feeds.

and I’ve seen an htaccess RewriteRule somewhere that works but you have to specify each feed separately, you’ll have to do a search as I can’t remember where it was, but it is possible.

If i keep hotlinking code before wordpress code. then it works.

Thanks again

RewriteEngine on
RewriteCond %{HTTP_REFERER} .
RewriteCond %{HTTP_REFERER} !^http://(www\\.)?MYDOMAIN\\.com [NC]
RewriteRule \\.(swf)$ /games/arquivo/hotlink.swf [L]

Why is not working ?

this is the possible line that i have coded but does not work.

RewriteRule !.*/thumb_\.(jpg|jpeg|gif)$ http://www.hqcelebphotos.com/error.png [NC,R,L]

Great article. Made sure to bookmark you on my new del.icio.us account

I got my htaccess file working and it’s stopping the hotlinking. Unfortunately when they visit the offender’s page, my replacement image gets cached in their hard drives. When they visit my site after reading (IMAGE AVAILABLE AT XYZ.COM), the images from my site are loaded from their cache instead of from my site, using the accepted referrer. Any way around this? I don’t want to institute something like “nocache” on my site (even if it would help) because it would eat up a lot of bandwidth I’m trying to conserve.

Haha long little comment but maybe you or someone else might have some thoughts!

Cheers,

It is fully compatible with apache mod_rewrite and also supports .htaccess!

RewriteCond %{HTTP_REFERER} !^http://(www\.)?yahoo\.com [NC]
RewriteCond %{HTTP_REFERER} !^http://(www\.)?google\.com [NC]

I Have Some Question !
When I Have Already One Customs Error Page In .htaccess File How Can I Add It One more .htaccess File In Our Server ?
Or Just We Have To Add In Same File ?

And Can You Pleas Preview One Example Pleas ?

For Example Take Yahoo.com !

RewriteEngine on
RewriteCond %{HTTP_REFERER} .
RewriteCond %{HTTP_REFERER} !^http://(www\.)?yahoo\.com [NC]
RewriteRule \.(hotlink.jpg)$ – [NC,F]

Is That OK ?
I Was Trying To My Site But It’s Not Working !
Pleas Give A Example If You Want !!

Thanks A Lot !
All The Best

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

can I remove these lines and replace them with the ones you provided? Do they cover the same kind of things?
thanks for any advice or ideas you may have!
