Server Side Script To Get IP From Image Request

. For an image hosted on server, I need a script that will get info about the client when that image is requested in an html email. Specifically, this script will: 1) Get the IP address of email reader. If they open in Outlook for example, ideally want to get the current IP of where they opened. If they open in browser email, or gmail, etc., I understand that we will only get the IP of gmail and that is ok. 2) Would like any other info that is available: - operating system - brower - time 3) Would like that info emailed immediately to a specified email address. Essentially, I want to implment the equivalent of what [login to view URL] does but I want control over the image that is used. Please indicate in your reply if there is any special server requirements that we will need.
