These are a few modules I have written for the Drupal open source community.
The Image Gallery module makes it easy to present groups of photographs together by category. The Image Gallery Management module makes it even easier by allowing users to move many pictures from one gallery to another in a single action, using thumbnails.

There are times when a website will have a drop-down selection list with dozens or even hundreds of items, making it difficult to find a specific item. This module solves the problem by adding a Javascript widget to any list on a website, enabling it to be searched by a keyword. It's visually compact, and self-explaining.
See the full explanation for a demonstration, and to download this.
(The following may not make much sense to you unless you have administered or contributed to a Drupal site before.)
This module enables you to substitute any node's content with a different node, when a predefined condition is met.
Let's say your site cars.example.com has a welcome message on the front page. With this module, you can swap the welcome message with a different node for people in, for example, the car sellers group. Or if the website has an alias, hybrids.example.com, you can swap the welcome message with something more specific to hybrid cars when people view the site from the aliased domain name.
Those are just simple examples, but you can use any PHP code as a condition for substituting a node. And you can even use a past revision of a node as the substitution target.
