Would you like to draw clock face hands on to an image (such as the one shown here, with the time in UK when you called the page up!)? It's easier than you think using PHP's GD module.

Instead of supplying a fixed image in your <img> tag, provide the URL of a PHP script that reads an image and adds the hands - like I've done to the left here. I've even provided the source code - here so you can do something similar if you wish!

This very example is also used on our site clock which generates one image per minute ... and it will be a long time before we have all the images we need without using the PHP "cheat" I've introduced on this page.
