Hotlink image branding

[impss]

Hello all, I was wondering if someone can help me out

Im looking for a way to put a little logo on the bottom left of only my gallery pictures and only on pictures that are hotlinked and displayed on other places on the net.
Is this possible to do? I believe Cardomain.com does this with there images.

Any help would be greatly appreciated
 
i dont mind that people hotlink my images, but i want to advertise while they do it.

This could be done on server sive via .htaccess and imagemagic... there are also some aniti-leech scripts can't remeber any of the top of my head but check google. These scripts basically replace the image from the user with a generic one that says something to the effect of no, maybe your logo. It's really just a matter of haining it point to image magic so that it generates a watermarked thumb... hell this seems like it would be such a common thing people may want to do that there may already be a solution posted on the imageMagic website somewhere.

I have seen where you can change the picture using .htaccess
But nothing the would add my watermark 

Most of the people that are hotlinking belong to another forum i frequent and i dont mind them doing it. I just what to add the logo so the people that dont know about the site, will then know.
