Definable Infoboxes adds 10 infoboxes to your site that are fully and easily definable. You simply upload your content files (currently supports .htm, .html, .jpg, .gif, .png, .swf) to a folder and then from the admin you can choose which file gets "included" into which infobox. You can upload and display html, php, image, or even flash files easily this way.

This is an easy way to add flash or images to your left or right columns.
