AJAX-ZOOM - thumb hover zoom gallery

Responsive thumbnails gallery plugin with hover zoom effect and various other options.

On click, the AJAX-ZOOM viewer opens in a lightbox such as responsive "Fancybox". The viewer can also open at fullscreen or as full browser window overlay.

All JavaScript is within the jquery.axZm.hoverThumb.js file, which is an AJAX-ZOOM extension. The documentation of the $.azHoverThumb options is at the bottom of this page.

Responsive width ranging from 12.5% to 100% depending on the resolution of the screen

Depending on resolution, the width changes over adjustable CSS3 @media Queries to 12.5%, 16.66%, 20%, 25%, 33.33%, 50% or 100%. The height is set instantly via the parentHeightRatiooption, which is a fixed width/height image ratio;

Example with the parentHeightRatio option set to 0.6 and images having different proportions. The zoomRatio option is set to 2.5

Images center within their parent containers. Background color refers to the parent containers CSS class, and the border is set via CSS padding.

Fixed width and height of the thumbnails

The width and height of the parent thumbnails are not responsive but set via CSS class as fixed px values. Neither parentHeightRatio nor parentWidthRatio apply below.

Fixed height of the thumbnails (the unit of the height may be responsive as %) and parentWidthRatio option set to "auto"

The "auto" value of the parentWidthRatio option also works in IE < 9.
