[/code]

附加CSS (Attaching CSS)

I attached 2 external CSS files

我附加了2个外部CSS文件 

<link rel=\"stylesheet\" media=\"screen\" type=\"text/css\" href=\"zoomimage.css\" /><link rel=\"stylesheet\" media=\"screen\" type=\"text/css\" href=\"custom.css\" />
<link rel=\"stylesheet\" media=\"screen\" type=\"text/css\" href=\"zoomimage.css\" /><link rel=\"stylesheet\" media=\"screen\" type=\"text/css\" href=\"custom.css\" />

[/code]

zoomimage.css, custom.css

zoomimage.css ， custom.css

添加jQuery (Adding JQuery)

I attached 3 external JS files

我附加了3个外部JS文件 

<script type=\"text/javascript\" src=\"eye.js\"></script><script type=\"text/javascript\" src=\"utils.js\"></script><script type=\"text/javascript\" src=\"zoomimage.js\"></script>
<script type=\"text/javascript\" src=\"eye.js\"></script><script type=\"text/javascript\" src=\"utils.js\"></script><script type=\"text/javascript\" src=\"zoomimage.js\"></script>

[/code]

And here are additional initialization code

这是其他初始化代码 

<script type=\"text/javascript\">(function($){var initLayout = function() {// example 1$(\'a.example1\').zoomimage();// example 2$(\'a.example2\').zoomimage({border: 20,centered: true,hideSource: true});// example 3$(\'a.example3\').zoomimage({controlsTrigger: \'mouseover\',className: \'custom\',shadow: 40,controls: false,opacity: 1,beforeZoomIn: function(boxID) {$(\'#\' + boxID).find(\'img\').css(\'opacity\', 0).animate({\'opacity\':1},{ duration: 600, queue: false });},beforeZoomOut: function(boxID) {$(\'#\' + boxID).find(\'img\').css(\'opacity\', 1).animate({\'opacity\':0},{ duration: 600, queue: false });}});};EYE.register(initLayout, \'init\');})(jQuery)</script>
<script type=\"text/javascript\">(function($){var initLayout = function() {// example 1$(\'a.example1\').zoomimage();// example 2$(\'a.example2\').zoomimage({border: 20,centered: true,hideSource: true});// example 3$(\'a.example3\').zoomimage({controlsTrigger: \'mouseover\',className: \'custom\',shadow: 40,controls: false,opacity: 1,beforeZoomIn: function(boxID) {$(\'#\' + boxID).find(\'img\').css(\'opacity\', 0).animate({\'opacity\':1},{ duration: 600, queue: false });},beforeZoomOut: function(boxID) {$(\'#\' + boxID).find(\'img\').css(\'opacity\', 1).animate({\'opacity\':0},{ duration: 600, queue: false });}});};EYE.register(initLayout, \'init\');})(jQuery)</script>

[/code]

步骤4.图像和光标 (Step 4. Images and cursors)

Also we need several images and cursors for these demos:

此外，这些演示还需要一些图像和光标：

zoomin.cur, zoomout.cur

zoomin.cur ， zoomout.cur

对于开发人员。 定制化。 (For developers. Customization.)
