Zooomr are apparently releasing an update on Monday which will activate notes on photos and something they are calling portals. Like Notes, an area of the photo is hotlinked to give you a scrolling view of another photo (such as a closeup shot of an area in the first photo). You can scroll around the closeup within the original photo and then click on it to zoom into the next photo – A unique implementation. The blog post by Kristopher has a link to the YouTube video of it in action.
