Enhanced podcast options

I created podcasts for my course and showed images during lectures, and after the semester ended I looked into converting those into movies or enhanced podcasts. Making a movie was easy enough with iMovie, but the file sizes were pretty large. I estimated it would have been about 16GB total for the whole semester for large movies. The enhanced podcasts were smaller - the 5.4MB audio-only file became a 6.5MB file when images were added. However, the quality of the images meant they were much less useful. Since I already make the images available via a published Google Presentation, I think I ended up doing it the best way. Students can subscribe to the audio podcast and get the audio, and they can navigate through the images at their own pace. I will try to add an audio cue when I switch images so it will be a bit easier for students who are listening to the recording.
