Article Update: Creating a Compound Field Module for CCK in Drupal

I recently wrote an article: Creating a Compound Field Module for CCK in Drupal. It's a programming tutorial on how to create a custom field module for the Drupal content management system and its Content Construction Kit module. In particular, the article covers how to create a custom field that packages an image upload, a caption, and taxonomy term, as one "compound" field. It's now been updated with additional notes on how to do this if your compound field does not include a file upload.
