Depending upon how it's done, displaying a page of thumbnail images can be very cumbersome. Allowing the browser to resize images requires the client browser to download the entire, full-size image, then clumsily resize the image to a specified size. This causes the page to load very slowly and creates unavoidable distortion in the resulting images. The other option is to make separate thumbnail images for each individual image. This is fine if you only plan to display a few images, but becomes unrealistic on a large scale or a site involving dynamic images. Fortunately there are ways around these problems using the GD library in PHP.

So far in Webmonkey, you've seen how PHP can be used for databasing and site navigation. It's pretty bland. In this article we're going to leave that dry stuff behind and concentrate on PHP's image-creation abilities.

This tutorial will tell you how to write text to a blank dynamically generated PNG image in PHP. This is fairly simple, so it will just be the first step in a series of tutorials dealing with images in PHP. The image functions require the GD library to be installed.

Many people do not realize that PHP can be used to create non-HTML data. This is especially useful for creating images on the fly. It could be simple bar graphs that display data from a database, or even simpler, just a way to create graphic buttons on the fly.
