My apologies if this has been discussed in the past. A lot of sites do not wish for their images, or other content, to be linked to from outside of thier site. If they use Apache and the mod_rewrite module, they usually have a directive, or several directives, in their httpd.conf like: RewriteCond %{HTTP_REFERER} !^http://www\.yoursite\.com.*$ RewriteRule ^/images/.* - [G] I have found that it is possible to circumvent the above rule by constructing your link like: http://www.yoursite.com//images/image.jpg The web browser will then make an HTTP request like "GET //images/image.jpg" HTTP/1.0", which does not match this rewrite rule, but is still valid. This does not appear to be a bug with mod_rewrite or even Apache proper, but it looks like it's inherited from either the filesystem driver, or perhaps your operating system's libc, which, at least on UNIX systems that I am familiar with, handles multiple occurences of "/" in a pathname as though it were a single "/". This can be fixed by modifying your ReWriteRule directives to reflect this behavior: RewriteCond %{HTTP_REFERER} !^http://www\.yoursite\.com$ RewriteRule ^/*images/.* - [G] Which will match multiple occurences of "/" in the path of the HTTP request.
