Below, is an image which shows your IP address. Therefore, it must have been generated on-the-fly. Generated images are useful for a number of things, such as creating anti-robot codes for web-forms. The code to do this sort of thing is very simple and self-explanatory. Save the code in a PHP file and then refer to that file in the <img tag of your HTML.
This example image retrieves your IP address and assigns it to a variable.
Image generation using a TrueType font
This adds a dash of creativity to your image - using a TrueType font which must be in the same folder as the PHP file you create. This example writes the text twice, once in grey and once in black, with a small off-set, to create a shadow effect.
