Gallery4All is a free open-source web-based image gallery, running with PHP and MySQL database support.
The first version of the script was released back in 2004 under the slogan “run you web gallery by calling just one function”.
“Gallery4All is a simple and rapid dynamically generated thumbnail gallery made with PHP & MySQL. It can be easely integrated in your design and script. The pictures are structured in categories, urls can be generated with mod_rewrite“
In January 2009 the script was totally rewritten, and has new features like the ability to automatically trim the images, keep them in multiple category (parent to childs) format, integration with Amazon S3 and Flickr.
