would be an RSS feed; either (or both!) from the photoblog frontpage picture or from the last picture of an individual user's blog, a feature that you could integrate in one of your future versions? or did we have it already and i missed it?
i'd like to integrate such an RSS feed on my igoogle portal page. similarly useful could be a little photoblog gadget that can be used on igoogle pages as a module, but an RSS feed address would do.
