Microsites - extending PhpBB to support image quizzes

One of the features I imagined any fansite should have is a quiz of some kind to test your knowledge of the series in question. One popular site I have is a Naruto quiz, which I made one evening just for fun. Adding images to that quiz required me to edit things in the database manually and copy images into the image directory manually as well. I want to improve that by creating a PhpBB extension that lets forum users create their own quizzes by uploading images. I have several motivations for making this.

First of course that it is one of the planned features for the microsites I've been talking about for the past few posts. Secondly it allows me to easily create new quiz sites similar to the Naruto Quiz, which seem to easily become popular. Thirdly I can use the feature right away on the forums which I host and get people to make their own quizzes - I'm sure they'll be more creative than me and create kick-ass quizzes.
