Hot linking protection only for some domains

The top 5 violators would cover 90% of hot linking

[jetteroheller]

Just discovered, that ony of my domains used last month about 5 GB for hot linked pictures.

Most violators are 5 domains´

Now I would like to redirect all with referers from this 5 domains accessing a jpg to an do-not-copy.png

But I did not find an example for exactly this.
Please could somebody help?

Adding

RewriteCond %{HTTP_REFERER} ^http://www\.hotlinker1\.com [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://www\.hotlinker2\.com [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://www\.hotlinker3\.com [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://www\.hotlinker4\.com [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://www\.hotlinker5\.com [NC]

ahead of the 'standard' code will make that code execute only if the referrer is one of those unwelcome sites. Note that most media players do not provide a referrer, so this may not work if you are trying to stop media-file hotlinking. If you're just trying to stop image hotlinking, where the images are loaded by the browser (not a media player), this should work fine.

But where is in the code, that only jpg are not allowe to link to

Where is the target to write?

Also one of the violators has many different subdomains.

How to match only with the domain name?

[jdMorgan]

# block any/all hotlinker1 subdomains
RewriteCond %{HTTP_REFERER} ^http://([^./]*\.)*hotlinker1\.com [NC,OR]
...
# block hotlinker5 domain and www subdomain
RewriteCond %{HTTP_REFERER} ^http://(www\.)?hotlinker5\.com [NC]
# return 403-Forbidden response to hotlink requests for .jpg files
RewriteRule \.jpg$ - [F]
