Implementing Cloud Zoom in Blogger
Cloud Zoom is a lightweight, highly customizable jQuery plugin that allows you to add image zooming in your web pages. You can use this plugin to create zoomable images with different features such as tint effect, inner zoom and soft focus. It is a cross browser plugin that works in all major web browsers including IE6.Cloud Zoom is very easy to implement and is very well documented. You can easily customize the appearance of the smaller image, lens and zoom window using CSS. It offers several configuration options enabling you to customize its behavior including: height, width & positions of zoom window; tint; opacity; amount of smoothness/drift of the zoom image as it moves; enable or disable titles.
Steps to Add it to Blogger:
1.Login to the Blogger account.
2. Now Go to Design > Edit HTML.
3.Now search for the </head> tag and paste the following code just Above/Before it.
<link href="http://dl.dropbox.com/u/27675057/Cloud%20Zoom/cloud-zoom.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script src="http://dl.dropbox.com/u/27675057/Cloud%20Zoom/cloud-zoom.1.0.2.js" type="text/JavaScript">
</script>
2.Go to the Post/Page you want to add the Cloud Zoom
Now go to Edit HTML tab .
3.Now copy the code from below and paste it there.
<link href="http://dl.dropbox.com/u/27675057/Cloud%20Zoom/cloud-zoom.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script src="http://dl.dropbox.com/u/27675057/Cloud%20Zoom/cloud-zoom.1.0.2.js" type="text/JavaScript">
</script>
Now When you see the code in the edit HTMLwindow it would be something like this
<a href=" large3.jpg"=""><img border="0" height="90" src="/small3.jpg" width="120" /></a>
Make it like this
<a class="cloud-zoom" href="large.jpg" id="zoom1" rel="adjustX: 10, adjustY:-4, softFocus:true"><img align="left" alt="" src="small3.jpg" /></a>
As you can see we added only a class="cloud-zoom" and add a id tag for adding gallery files.
For multiple images together add the following code after the above code
<a class="cloud-zoom-gallery" href="http://dl.dropbox.com/u/27675057/Cloud%20Zoom/20.jpg" rel="useZoom: 'zoom1', smallImage: 'http://dl.dropbox.com/u/27675057/Cloud%20Zoom/20%20%283%29.jpg' " title="Thumbnail 1">
<img alt="Thumbnail 1" src="http://dl.dropbox.com/u/27675057/Cloud%20Zoom/20%20%282%29.jpg" /></a>
<a class="cloud-zoom-gallery" href="http://dl.dropbox.com/u/27675057/Cloud%20Zoom/74.jpg" rel="useZoom: 'zoom1', smallImage: 'http://dl.dropbox.com/u/27675057/Cloud%20Zoom/74%20%283%29.jpg' " title="Thumbnail 2"><img alt="Thumbnail 2" src="http://dl.dropbox.com/u/27675057/Cloud%20Zoom/74%20%282%29.jpg" /></a>
