/* END EasySlider */

Step 2 - Adding JavaScript

• Now find for </body> tag
• Add below code just after/below </body> tag.

<!-- Start easy content slider -->
<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.6/jquery.min.js' type='text/javascript'></script>
<script src='http://accordion-template.googlecode.com/svn/trunk/easySlider1.7.js' type='text/javascript'></script>
<script type='text/javascript'>
//<![CDATA[
$(document).ready(function(){
 $("#slider").easySlider({
 auto: true,
 continuous: true
 });
});
//]]>
</script>
<!-- End easy content slider  -->

Now save your template.

Adding The Gadget

• Now go to Page Layout
• Add a Gadget > HTML/JavaScript
• Paste below piece of code and save it.

    <div id="slider">
<script style="text/javascript" >
var showpostthumbnails_gal  = true;
    var showpostsummary_gal   = true;
 var random_posts         = false;
 var numchars_gal   = 150;
 var numposts_gal   = 10;
function showgalleryposts(json) {
    var numPosts = json.feed.openSearch$totalResults.$t;
    var indexPosts = new Array();
 document.write('<ul>');
    for (var i = 0; i < numPosts; ++i) {
        indexPosts[i] = i;
    }
 if (random_posts == true){
    indexPosts.sort(function() {return 0.5 - Math.random()});
 }
    if (numposts_gal > numPosts) {
        numposts_gal = numPosts;
    }
    for (i = 0; i < numposts_gal; ++i) {
        var entry_gal = json.feed.entry[indexPosts[i]];
  var posttitle_gal =  entry_gal.title.$t;
        for (var k = 0; k <  entry_gal.link.length; k++) {
            if ( entry_gal.link[k].rel == 'alternate') {
                posturl_gal =  entry_gal.link[k].href;
                break;
            }
        }
  if ("content" in entry_gal) {
            var postcontent_gal = entry_gal.content.$t
        }
        s = postcontent_gal;
        a = s.indexOf("<img");
        b = s.indexOf("src=\"", a);
        c = s.indexOf("\"", b + 5);
        d = s.substr(b + 5, c - b - 5);
        if ((a != -1) && (b != -1) && (c != -1) && (d != "")) {
            var thumburl_gal = d
        } else var thumburl_gal = 'http://i1133.photobucket.com/albums/m596/abu-farhan/Images_no_image.gif';
        document.write('<li><div id="slide-container"><span class="slide-desc"><h2 style="margin:10px 0px;">');
        document.write(posttitle_gal + '</h2>');
        var re = /<\S[^>]*>/g;
        postcontent_gal = postcontent_gal.replace(re, "");
        if (showpostsummary_gal == true) {
            if (postcontent_gal.length < numchars_gal) {
                document.write(postcontent_gal);
                document.write('</span>')
            } else {
                postcontent_gal = postcontent_gal.substring(0, numchars_gal);
                var quoteEnd_gal = postcontent_gal.lastIndexOf(" ");
                postcontent_gal = postcontent_gal.substring(0, quoteEnd_gal);
                document.write(postcontent_gal + '...');
                document.write('</span>')
            }
        }
   document.write('<a href="' + posturl_gal + '"><img src="' + thumburl_gal + '" width="480px" height="360"/></a></div>');
        document.write('</li>');
    }
 document.write('</ul>');
 
}
</script>
<script style="text/javascript">
 var numposts_gal = 6;
 var numchars_gal = 150;
 var random_posts = false; // random posts
</script>
<!-- replace with your web address (marked with red color) -->
