Adding Drop Shadows with PHP

(Page 1 of 7 )

This tutorial will teach you how you can add drop shadows dynamically to your images using PHP's GD image processing functions.

Imagine a scenario where you have an online photo album and the layout calls for drop shadows to be placed behind each image. It would be a hassle to manually add the shadow to each image... and actually modifying the original picture might not be possible depending on the circumstance. But if there're a few extra processor cycles available on the server, why not script the shadow using PHP?

The idea is simple: take the original image, create a slightly larger new image, draw a shadow on the new image, overlay the original image and send the results back to the requesting client. The drop shadow can be added on the fly!
