Bindings

src	- source url for the image to be displaed. mandatory for this component to work properly.
height	- height of the image to be displayed in the page.
width-	width of the image to be displayed in the page.
zoomWidth	- width of the zoomed image. defaults to 200.
zoomHeight	- height of the zoomed image. defaults to 200.
thumbnailSrc	- source url for the thumbnail. if null, src binding with height and width is used.
title	- title for the image. used as tooltip in thumbnail mode [optional]
enableZoomForImage	- true/false. if true, clicking on thumbnail will popup the full size image. If false, clicking is not allowed.
