1. Allow your blog readers to annotate photos
2. Zoom in on photos within the widget
3. Track view counts for photos, wherever they're shared
4. Sell photos directly from the widget

Phlook's best bet might be to focus on the high end, professional photography market, using the integrated store to create thousands of entirely distributed stock photo sites.
Bloggers: would you use Phlook on your blog? Photographers: would you sell your photos via a Phlook widget?
