Add first the last jQuery release, then the jQZoom script(don't forget this),the correct order is important.Look at the installation code below. <script type='text/javascript' src='js/jquery-1.5.xx.js'></script> <script type='text/javascript' src='js/jquery.jqzoom-core.js'></script> Add jqzoom.css to your header. <link rel="stylesheet" type="text/css" href="css/jquery.jqzoom.css"> 　 How to use Using jQZoom is easy,but you need to specify the HTML anchor element,that is going to generate the zoom revealing a portion of the enlarged image. <a class="MYCLASS" title="MYTITLE" href="images/BIGIMAGE.JPG"> <img title="IMAGE TITLE" src="images/SMALLIMAGE.JPG"> </a> The anchor element wraps the small image you would like to zoom.Following this schema the necessary and base elements are: SMALLIMAGE.JPG: Represents the small image you would like to zoom. BIGIMAGE.JPG: Represents the big image that jQZoom will reveal. MYCLASS: Represents the anchor class,that would be used to instantiate the jQZoom script to all the elements matching this class(you can use an ID as well). MYTITLE/IMAGE TITLE: Anchor title and/or image title that will be used to show the zoom title close to the jQZoom Window. PAY ATTENTION: The SMALLIMAGE must be a scaled versione of the BIGIMAGE. Now load the plugin at window load. $(document).ready(function(){ $('.MYCLASS').jqzoom(); }); This will instantiate jQzoom in default(standard) mode.You can pass more options(Documentation section),to create special or custom effects as in the example below. $(document).ready(function(){ var options = { zoomType: 'standard', lens:true, preloadImages: true, alwaysOn:false, zoomWidth: 300, zoomHeight: 250, xOffset:90, yOffset:30, position:'left' //...MORE OPTIONS }; $('.MYCLASS').jqzoom(options); }); 　 Multiple thumbnails support If you want to create galleries, jQZoom can manage it for you. 1. Attach the gallery ID to your main anchor "rel" attribute. <a class="MYCLASS" title="MYTITLE" href="images/BIGIMAGE.JPG" rel="gal1"> <img title="IMAGE TITLE" src="images/SMALLIMAGE.JPG"> </a> 　 2. Manage your thumbnails "class" and "rel" attributes. The class "zoomThumbActive" is attached to your thumbnails by jQzoom. By default specify this class to the selected thumbnail(it should be the same image in your main anchor element) <a class="zoomThumbActive" href="javascript:void(0);" rel="{gallery: 'gal1', smallimage: './imgProd/SMALLIMAGE1.jpg',largeimage: './imgProd/LARGEIMAGE1.jpg'}"> <img src="imgProd/thumbs/THUMBIMG1.jpg"> </a> The structure of the thumbnail rel attribute is very important.The base elements are gallery: the ID of the gallery to which it belongs. smallimage: the path to the SMALLIMAGE to be loaded on the when you click on the thumbnail. largeimage: the path to the LARGEIMAGE 　 rel="{gallery: 'gal1', smallimage: './imgProd/SMALLIMAGE1.jpg',largeimage: './imgProd/LARGEIMAGE1.jpg'}"
