Hey,
So I am using PHP although any language solution would be great. I am looking at displaying whether or not a cookie from a specific ad network is present on your web browser. A good example is with AdChemy. They are a part of the NAI (Network Advertising Initiative) so by going to http://alps.adchemy.com/alps-cs/auuid/nai-status that page will redirect you to either http://www.networkadvertising.org/verify/cookie_optout.gif if you have opted out of their network or http://www.networkadvertising.org/verify/no_cookie.gif if no cookie is present or http://www.networkadvertising.org/verify/cookie_exists.gif if they have a cookie on you.
I want to be able to load the <img src="http://alps.adchemy.com/alps-cs/auuid/nai-status" /> and depending on which image loads it will display the word Cookie, No Cookie, or Opted out. Does anybody know how I would even go about doing this?
