How can I get a picture from the site in my program?
<p>Good afternoon.
There is a site that hosts announcements <a href="http://roswebrealty.ru/" rel="nofollow">http://roswebrealty.ru/</a>
I need to get a phone number on the page any announcement, for example <a href="http://velikie-luki.roswebrealty.ru/o82682" rel="nofollow">http://velikie-luki.roswebrealty.ru/o82682</a>
The phone number is represented as a picture. I wanted to get the link to the picture and save this picture and recognize this picture. But when I started to get a link to the picture in my program, I saw that this picture generated java script.
Here is the code in which I'm trying to get a link to a picture in my program:</p>

<pre><code>.....
HtmlNode bodyNode7 = doc.DocumentNode.SelectSingleNode(@".//*//table[6][@class='objectView']//tr[2]//td");
Console.WriteLine(bodyNode7.InnerText.ToString());
.....
</code></pre>

<p>I use HtmlAgilityPack library (C#) for parsing the picture link.
I opened the source code of this page (http://velikie-luki.roswebrealty.ru/o82682) and saw Javascript that generates picture:</p>

<pre><code>&lt;tr id="ctl00_cphBody_FlatSell_Obj_adapterObject_trPhones" style="background-color: white"&gt;
        &lt;th&gt;Телефоны:&lt;/th&gt;
        &lt;td&gt;
                    &lt;script language="javascript" type="text/javascript"&gt;document.write(decs("0x88e36b6d468b03acca9737a99ba0fffe05cb3a53de8858b798194826c94719e2193434b3377d69745a1a28879291ecfd69c703de931ac8f551fe22229ef49160"));&lt;/script&gt;
        &lt;/td&gt;
&lt;/tr&gt;
</code></pre>

<p>In the javascript is used function decs() to generate the picture. Here is the code:</p>

<pre><code>function decs(a){
return deco(key,hexToString(a),0,1,iv)
};
</code></pre>

<p>If I understand correctly, this function created a link to an picture with the phone number or this function created this picture. In this case, the function uses a parameter "key". How to create this parameter, I do not know.</p>

<p><strong>Question:</strong> How can I get the link to this picture with a phone number or download this picture with a phone number in my program?</p>
