This PHP script was developed to compensate for the lack of image overlay capabilities of some less sophisticated IP cameras. It takes the original image as uploaded by the camera from the web server and uses the GD library to modify the image on the fly before displaying it to the website visitor.

It supports picture watermarking with configurable image position, text watermarking (original image "modified" date + freely configurable text) and a configurable timed overlay image which is supposed to be used as a "downtime" picture.
