You probably saw those images which can show your local IP address on the interent before. Is it hard to make? Not really! You can achieve this by using PHP, since PHP has a function named "ImageCreateFromJPEG" which allow you to generate an image dynamically.

It is not hard to find your IP address using PHP. However, the location is a big problem. I found a Chinese IP database, and it contains a list of IP and its associated country or city. The problem is that it only supports Chinese so far.

Then I pass 2 parameters via the URL. One is the image's URL address, the other one is the text you want to add on the final generated image. The URL format is: http://www.sunnyspeed.com/idea/53_200609_ip/ip_speed.php?pic=your image's URL&text=your word

Example:

A image URL address: http://www.sunnyspeed.com/idea/53_200609_ip/ffmm.jpg

The text you want to add is: 大家好啊！ (have to be Chinese so far)

Therefore you have the whole URL address for the dynamic image:

http://www.sunnyspeed.com/idea/53_200609_ip/ip_speed.php?pic=http://www.sunnyspeed.com/idea/53_200609_ip/ffmm.jpg&text=大家好啊
