isn't the simplest way just to have an ASP page check the session
variables and then (based on HTTP_REFERER) serve either the correct
image or some other resource if this being linked from outside your
site?

the only real problem here is that the simplest approach is the
easiest to defeat e.g. a simple .redirect will allow a choice of
resources and is simple to code and setup but equally is simple to
bypass if you understand http.

an alternative may be storing the images in a non-file format such as
in a database enabling them to be streamed out on demand.

Subject: IIS Security for Images


I am looking fo ra way to keep the security tight and that way people
will have no way to link to my images from auction sites.

I think it may be done using an ISAPI filter but not really sure
where
to look.  I have tried searches for "hotlink"   &  "Remote-Linking".

Any help is greatly appreciated.

Thank you
