How to theme Drupal 7 for any situation using preprocessing functions and template file suggestions

This week we give you a set of tools you can use to laser-focus theme changes for any situations. Want to serve up a different page template to anonymous users? Want to add some markup to images for certain content types? When the president of Burundi visits your site in April, do you want to add some festive flourishes?

To tackle critical (and whimsical) theme changes for virtually any situation, we cover using template suggestions and go deep into preprocessing functions, illustrating both with practical examples and conceptual visuals. We also discuss the rules of thumb when it comes to naming each (something that can be tricky for even the veterans among us).

Most of the videos below are subscriber-only, but our example-driven crash course on preprocessing functions is available for free here. Below is the full new set for this week. Enjoy!
