watermarking images using .htaccess

I know that there are a few people that have been hotlinking to the images on my site and there are probably thousands more that have copied and used my images offline.

I once read that it is possible to watermark any images that are hotlinked and I think it was also possible to add the watermark if someone right clicked and saved the image, but I can't find a script anywhere that does this.

So I am looking to be able to add a watermark to images if they are hotlinked to or if they are saved by someone else.

Does anyone know if this would be possible?

Thanks in advance

I think visohotlink is what you're searching for Wink

Thanks dcz,

I will check that out later.

The demo on that site is not currently working and so I'll check it out at a later date.

Thanks

The demo is now available. There was a small problem.

Check it on http://www.visohotlink.org

I think that I will just add a bit of code to the .htaccess file so that it displays another image if someone hotlinks it, apart from a couple of sites where I have hotlinked pictures myself!

If someone knows tha lines of code that I need they would be much appreciated Wink

Thanks

You can try this... shot in the dark.. I'm a little fuzzy with this... this is from my Cpanel. So I dont know for sure if this may work for you. You would enable hotlinking but may need to let your own site view the images... so

RewriteCond %{HTTP_REFERER} !^http://your-site.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://your-site.com$ [NC]
RewriteCond %{HTTP_REFERER} !^http://www.your-site.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://www.your-site.com$ [NC]

RewriteRule .*\.(jpg|jpeg|gif|png|bmp)$ http://www.your-site.com/you.gif [R,NC]

The image URL that will show on any other site that is hotlinking.
