We now have enough basic knowledge to begin integrating multimedia in our Drupal sites. We have learned about Nodes, which are the basic building blocks for content. We discovered that several contributed modules, including the invaluable CCK and Views modules, may be used to create and format our content. We now know that blocks are displayed in regions, and that themes control all the output of a page. We have further learned that any theme function in Drupal may be overridden at the theme level, using either a direct override (with a phptemplate_ or mytheme_ function), or in many cases by creating a template file ending with tpl.php.

In the next chapter, we will delve into the rich world of images.
