Gallery: I wrote this gallery for María so she can share pictures of the children with her friends without having send them by email. It is the simplest image gallery ever. It has a password protected admin section to add and delete images and there is no need for a MySQL database. You can see it in action here.
Installation: Download the script (link below) and unzip it. Maintain the directory structure. Edit the username and password at the top of admin/index.php. Move the whole lot into the directory where it will be located. The two image directories will need to be readable/writeable by the webserver (0777).
Warranty: No warranty of any kind is expressed or implied with regard to this script. The script is purely an example of how I created a gallery for my own purposes.
