Greetings. Zooomr.com has a very useful feature to upload a mp3 file for every photo which will turn into a small flash player once the photo is posted. It is called as the Zooomrtation and samples are
here.
This would really be a cool feature to add to be able to upload an audio mp3 file for every photo which will turn into a flash player which can autostart or be played while viewing the video. The photo can be explained in audio and I think that will be quite effective.
