Using TimThumb with WordPress MU

A few days ago, I saw a post on Smashing Magazine outlining ten tips to give your WordPress blog a little more personality. While most of the tips don’t really apply to the blogs on which I’m currently working, tip number two piqued my interest.

Tip number two explains how to display a list of “related posts” at the bottom of each post, and tells you how to add icons to each of those related posts. Unfortunately, when I attempted to implement the tip on one of my WordPress MU blogs, I found that it didn’t work for a few reasons.

  1. The tip uses a meta element called “post-img” which, as I’ve found since attempting to implement the tip, isn’t a standard WordPress element.
  2. TimThumb doesn’t work with WordPress MU out-of-the-box.

So, I set out trying to figure out how I should implement the tip. Following are the results of my tinkering.
