Adding ID selector to image chosen in Photo Module

This thread is a follow-up to the one I previously started about updating and image on a page on an interval. You and I had discussed a jQuery option to do this using an ID selector (I was coding this manually in an HTML module). You suggested that I use the Photo module instead and target the ID assigned to the image by that module (the img itself not the container). Sadly, this hasn’t worked out so well. There is no ID selector associated with the img. There is a Class selector which I’ve tried to target, but the image refresh doesn’t seem to work with that.
