Somone is sending harasing emails and i want to 'narrow down' who it could be. I want to send them an anonymous email with a image link. This should cause their browser to send me some information about them. (<img src='myserver/recordingfile.php' />)
Can anyone tell me what are all the possible bits of information i could get from this technique. So far I am aware of , IP, browser type, perhaps time zone...
can someone tell me if there are more variables that come through with reveling information?
Thanks.
