It doesnt work well as it thinks I'm about 200 miles away from where I am. Yeah its IP based and the jpg is built on the fly after checking your browser information that is sent when retrieving the image. Easy pie.

Its quite close for me.. just does a lookup on your IP and copys the text into an already created JPG with a text box. Simple HTML really.

The picture has to be created and something does a lookup on the IP!
Unless he made a load of jpgs that contain every local ISP local across the world ?
The IP belongs to a sever and using DNS lookup the code in that link can remove the rubbish and in most cases provide a close match.

you can draw onto images on the fly, quite simple really.
Those images with letters in do the same...
It knows where your ISP is...

Nope. It would be server side script; asp,php etc rendering the jpeg on the fly. No html involved.
