Yes - I've seen this here at It's actually got a very slick feel to it. There is a jquery plugin called cloud zoom from Professor cloud - You want the inner zoom option. This is what the website above is using.


Selecting, Zooming, and Panning You pretty much have the right ideas. The Windows User Experience Interaction Guidelines provide standards for this. For example, page 437 specifies: Single-left-click selects. Single-right-click opens the context menu. Double-click (left or right) selects and performs the default command. Single-shift-click (left or right) ...

Although KR-pano is Flash-based on a desktop-computer, it gives you plenty of options to publish on iOS-devices and Android. You can see a view examples on my website. On ...
