title: Pinch or mousewheel to zoom
body: <p>I need the functionality like this demo: <a href="http://preview.codecanyon.net/item/pinch-zoomer-jquery-plugin/full_screen_preview/6623080" rel="nofollow">http://preview.codecanyon.net/item/pinch-zoomer-jquery-plugin/full_screen_preview/6623080</a></p>
  
  <p>In desktops, the image can be zoomed in/out by the mouse wheel and on touch screen devices, 2 fingers gestures can be used to zoom in/out.</p>
  
  <p>I would use the library mentioned, but $6 seems a bit too much. I did find some other open-source libraries but they don't have both the features.</p>
  
  <p>I am building a static site that dynamically (using javascript) loads a single image.</p>
