Flash technology is an excellent way to create animated content among many other possibilities.Personally I prefer to use proprietary technologies.

Fortunately, every day there are new ways of doing the same thing, but using these standards and making presentations are more usable and accessible without sacrificing appearance. One such script is JS Coverflow with which we can implement an elegant image carousel.

Features:

• This tested browsers: Firefox 3, Opera 9.5 and Safari 3
• Only works with images with the same height and width
• Used easily with the mouse wheel or using the scroll arrows;
• Personalize the labels and the onclick event that fires in the center of the image in the foreground.
• This script has been tested with other libraries as Javascript: jQuery, MooTools, Dojo and Prototype.

It is an interesting alternative to Lightbox since it has rounded edges and the overall appearance is somewhat different. This gallery is very easy to implement and is distributed under a Creative Commons Attribution 2.5.

Simple Directory Listing is a PHP script that works as an online file manager.

It is only one file, just upload & use, and requires PHP to run.

The script can work in read-only or full mode and can be limited to manage a folder.

Besides the functions of a standard file manager script, it also has a FTP layer that makes it possible to connect to remote hosts.

And, the script has RSS support.

Such scripts are very useful when you want to make “files of a project”  reachable by customers where FTP usage may be limited or seem advanced from the eyes of the customer.

Requirements: PHP 4+
