preventing direct link to images

geocities manages - how?

[musicales]

I discovered today that geocities manages not to display an image if it's linked to directly from a web page, even to the extent that a link posted in a forum to the image didn't work ( but did work if you copied and pasted it into the address bar).

Anyone know how to do this? (I use IIS by the way)

There are multiple ways to accomplish what you've seen on geocities - however "mod rewrite" seems to be the most common way.

I've actually had to impliment this on our server to prevent other sites from directly (hot) linking to our images. I tried MANY different things but mod rewrite is what worked.

Now, we use unix servers with apache - so mo rewrite is quite common. I wasn't sure if mod rewrite was available for IIS so I did a quick search on google and found it is available. Without giving a link do a search for "mod rewrite iis mods" on google.

another search you can try is just iis hotlink

use asp.net, have the asp.net process jpg requests and write an event handeler to see where the referer is coming from
