Mail Tracing

Hi All,

Actually today when i was chatting to one of friend i got one request from abc@gmail.com to add as friend at Gtalk. I accepted that And then started i got some nude images from that abc. Now when i was getting these mails i was thinking to figure out who (s)he is ???

i tried to check the mail header but as everyone knows that google removes the sender information from the mail header so hopefully i didn't find any thing useful there. Now the real mystery begins but after one minute thinking i got fairly simple idea. i have one server for http://xyz.com there i kept one image and then i embedded the link of that image in my email and sent to the abc@gmail.com and bingo!!! as soon as that fellow opened the mail i got the IP on my server's Access log and i know with whome i am dealing with. :)
