Edit Cuber slider of Namisan Blogger template

First host your images at some free hosting site like public folder of DROPBOX(join dropbox using  http://db.tt/h8rHMPR7)
Note down the URL after hosting image(eg: http://dl.dropbox.com/u/3255460/top_container.jpg)(hover the cursor on image file on your dropbox and there you will see share or public link, from there you will get the proper link. The link should be such that image should directly open when the link is clicked) and put them in place of already existing URL in file 'config1.xml' by opening it with notepad which can be downloaded at (http://dl.dropbox.com/u/31323979/cu3er/config1.xml)(right click on the link and click save target as to save the XML file)
Now host this edited file on the public folder of dropbox.com

Note down new URL of config1.xml and put it in the html of your blog where u will notice below given script.. u can also edit the dimensions of cuber slider in place of 900 and 400.

<script src='http://dl.dropbox.com/u/31323979/cu3er/js/swfobject/swfobject.js' type='text/javascript'/>
<script type='text/javascript'>
        var flashvars = {};
        flashvars.xml = &quot;put link of edited config1.xml here&quot;;
        flashvars.font = &quot;font.swf&quot;;
        var attributes = {};
        attributes.wmode = &quot;transparent&quot;;
        attributes.id = &quot;slider&quot;;
        swfobject.embedSWF(&quot;http://dl.dropbox.com/u/31323979/cu3er/cu3er.swf&quot;, &quot;cu3er-container&quot;, &quot;900&quot;, &quot;400&quot;, &quot;9&quot;, &quot;http://dl.dropbox.com/u/31323979/cu3er/js/swfobject/expressInstall.swf&quot;, flashvars, attributes);

</script>

I would suggest not using this template though the template looks awesome because there is some problem in the script which doesn't show all your posts on your blog. I faced the same problem and ultimately was forced to change the template. For more info contact me.
