If you visit a photo page such as http://gwulo.com/atom/15456, you'll notice that you can no longer zoom in to the image.
The zoom viewer is still available, it's just been moved to its own screen. Look above the image and you'll see a button marked "Zoom". Click that to see the zoom viewer again.
This is to solve a problem that has puzzled me for a while. When I search for photos using Google's image search, Gwulo's images rarely appear in the results. It's because the zoom viewer makes our photos invisible to Google.
This change makes lets Google 'see' our photos, so they can start appearing in the search results again.
Please let me know if you notice the change has caused any problems.
