About the only effective way of protecting your images on the web is to watermark the images themselves. Any other form of “protection” is useless because the images are downloaded to your visitors’ computers in order for their browser to be able to display the web page and that image file can therefore be easily accessed from their computer completely independently of any so called protection built into the web page.

One problem with watermarking images is that you then need to keep multiple copies of each image, one with the watermark and one without.

In this tutorial we look at some simple PHP code that will allow us to do away with the need for watermarked copies of our images on our web site by automatically applying the watermark to the image when it is requested. This is not the most efficient solution but is the easiest to apply.
