1. CCK - Content Construction Kit - The Holy Grail

If you’re a drupaler and you don’t have CCK installed then you are one poor soul. Disclaimer: If you use Flexinode please don’t hate get all hot and bothered. The reason that I chose CCK is because it appears as if Drupal is going towards using CCK for custom content going forward, as can be evidenced in Drupal Version 5. In combination with this point, CCK has the best image attach properties of all the custom content with the imagefield module.

2. Views - If you don’t use Views then your Drupal site is probably very sad.
