How to pin a particular image to Pinterest in ASP.Net

I have a image on my page. I want to pin it to Pinterest. I also want that after pin, the page should redirect to my website page. How i will do it, please suggest me. I am using the following code.

<script type="text/javascript">
    (function (d) {
        var f = d.getElementsByTagName('SCRIPT')[0], p = d.createElement('SCRIPT');
        p.type = 'text/javascript';
        p.async = true;
        p.src = '//assets.pinterest.com/js/pinit.js';
        f.parentNode.insertBefore(p, f);
    } (document));
</script>

 <div style=" float:left; width:30px;position:relative; top:45px;left:12px;"><a href="//www.pinterest.com/pin/create/button/?url=<%=strPintURL%>&media=<%=strPintImage%>&description=Girls%20Room%3A%20Image" data-pin-do="buttonPin" data-pin-config="above"><img src="//assets.pinterest.com/images/pidgets/pinit_fg_en_rect_gray_20.png" /></a>
        <script type="text/javascript" async src="//assets.pinterest.com/js/pinit.js"></script></div>

 strPath = HttpContext.Current.Request.Url.AbsoluteUri;
        strPintURL = strPath.Replace("http://", "http%3A%2F%2F");   

 strPintImage = "http%3A%2F%2Fmywebsite.com/images/AJKids/GirlsRoom/" + dataTable.Rows[CurrentPage]["Image"].ToString(); 

 public string  strPintURL, strPintImage;
