I have a problem trying to reverse engineer this code to use for my blog:

Code:
  <div class='imageElement'>
                <h2>&lt;script&gt;var startposts = 0; numposts = 1; var showposttitle = true; showpostdate = false; var showpostsummary = false; var numchars = 0; &lt;/script&gt;&lt;script src=&quot;http://mahusay-fbt.blogspot.com/feed...k=rp&quot;&gt;
&lt;/script&gt;</h2>
                <p>&lt;script&gt;var startposts = 0; numposts = 1; var showposttitle = false; showpostdate = false; var showpostsummary = true; var numchars = 150; &lt;/script&gt;&lt;script src=&quot;http://mahusay-fbt.blogspot.com/feed...k=rp&quot;&gt;
&lt;/script&gt;</p>
            <a class='open' href='#' title='Read More'/>
            <img class='full' src='http://2.bp.blogspot.com/_t47uhxwKFVM/SmFaiXGB3gI/AAAAAAAABDg/EZD8TG8WL2o/s1600/image1.jpg'/>
            <img class='thumbnail' src='http://2.bp.blogspot.com/_t47uhxwKFVM/SmFaiXGB3gI/AAAAAAAABDg/EZD8TG8WL2o/s1600/image1.jpg'/>
        </div>
This is part of a series of images in a slideshow found here:
http://mahusay-fbt.blogspot.com/

I want to use this for my site and am having trouble trying to figure out how to edit this for my own site.

I can change the image and link code to mine easily but am having trouble editing this part:

Code:
                <h2>&lt;script&gt;var startposts = 0; numposts = 1; var showposttitle = true; showpostdate = false; var showpostsummary = false; var numchars = 0; &lt;/script&gt;&lt;script src=&quot;http://mahusay-fbt.blogspot.com/feeds/posts/default?orderby=published&amp;alt=json-in-script&amp;callback=rp&quot;&gt;
&lt;/script&gt;</h2>
                <p>&lt;script&gt;var startposts = 0; numposts = 1; var showposttitle = false; showpostdate = false; var showpostsummary = true; var numchars = 150; &lt;/script&gt;&lt;script src=&quot;http://mahusay-fbt.blogspot.com/feeds/posts/default?orderby=published&amp;alt=json-in-script&amp;callback=rp&quot;&gt;
&lt;/script&gt;</p>
There are so many nonsense characters that I can't see where/how to add my own url.

Thanks in advance for any help you guys can give me!
