iTunes Podcasting ChapterTool
Enhanced podcasts are simultaneously one of the coolest and most frustrating implementations in the iTunes/iPod universe. Documentation on how to do them is poor, Apple released a horrid command line tool that requires a third party tool for mere mortals to understand. Except for pt that is. The MAKE blog comes through with another great hack, providing practical instructions for adding images and chapter points to your podcast for better playback in iTunes or on an iPod photo. This means you'll need at least two versions of you podcast though because the format isn't supported by non-Apple products.
