Copyright It! is a tool that allows you to add copyright notices directly onto your images without any fussing around in image editors. You can either use the program yourself, or add it to your web sites to add functionality. The program lets you enter the copyright text, the font size, and the color of the notice. The program also uses a unique temporary file system, so your server doesn't get overloaded with files.
The PHP Exif Library (PEL) provides an easy-to-use library written in pure PHP which will allow you to both read and write the Exif headers commenly found in JPEG and TIFF photos taken with digital cameras. All tags can be added and deleted.
This collection of PHP scripts allows you to easily log and control hotlinking of images on your Apache hosted web site.
You can see who is linking your images and how much bandwidth they are leeching.
You can also control what happens to individual hotlinkers - you can block images,
substitute images, or best of all you can watermark hotlinked images with a text message such as your URL. Whenever someone hotlinks one of your images, you can promote your site!
These scripts are free for any purpose under the terms of the LGPL but a link back to us here at SillyJokes would be nice.
phpWatermark aims to provide a simple way of marking an image with a digital "watermark" to prevent unauthorized use. It is implemented as a php class and should be usable inside most php scripts. Images are accepted either as a filename or as a reference to a php resource.

Steganography in PHP??? you bet.
This is a PHP script that can hide files in images. It takes a JPG and converts to PNG. It requires GDlib and is almost totally pointless, but I was bored and hey, someone might actually have a use for it. enjoy :-)
Change Progessive Images to Non-Progressive Images and Thumbnails for PHP-Flash applications. This script can also be used to dynamically create cropped thumbnails for any application.
While this script was only written for Jpeg images, because progressive JPEG images can not be displayed in Flash applications using ActionScript, it can be changed for other image types.
I quickly wrote this script to help out a web hosting client whose developer was insisting I install ImageMagik on our server. It allows you to put up resized versions of jpegs without going through the fuss of working on them with a graphics editor. There are three functions: image_resize allows you to specify a new width and height for an image. image_horizontal_resize and image_vertical_resize are wrappers for the first and allow you to specify only the width or the height. The last parameter in these functions is a boolean, and determines if the original image is made available for download or not.
This script uploads to your website and is accessed through a specifically formatted URL. You can then view the EXIF information of any of the images hosted on your site. Use for educational purposes, or just to look at the pretty table created.
