Photo Dropper is a Wordpress plugin that allows you to easily search for and place Creative Commons licensed photos from Flickr in your weblog posts. The Plugin provides a search field within the post interface that allows you to search via key words. It provides the option of placing a small, medium or large images in your post and automatically includes the attribution.

The setup options allow you to automatically exclude images that are not commercially usable and also allows you to sort your search returns based on "interestingness."

This is something I plan to add to our school weblogs that are powered by Wordpress.
