Sorry, all your post does not seem to make sense, starting from its title. "Convert" is just the absurd, as many other things. It's possible that you want to do something reasonable, only your wording is wrong. Then you can edit it using "Improve question".

You want to get all images from a page? Search that way, don't search for convert.

You can use the WebClient class and possibly even the HTML Agility Pack to parse our the images. http://htmlagilitypack.codeplex.com/

A URL is an address to a file, whether it is local (your webserver) or remote (someone elses webserver). A URL "points" to an image, in the same way that a file path and file name points to a file on your hard drive. The URL allows your web application to display the image on a web page.

For example:

HTML

 Remote image:
 <div>
     <img src="http://someremotewebsite.com/images/remoteImage.jpg" alt="Alternate text in case your image does not display" />
 </div>

Local image (assumes using .NET Framework) :
 <div>
      <img src="~/images/localImage.jpg" alt="Alternate text in case your image does not display">
 </img></div>

you can create like this....

HTML

<html xmlns="http://www.w3.org/1999/xhtml">
<head  runat="server">
    <title></title>
</head>
<body>
    <form id="form1"  runat="server">
    <div>
        <asp:scriptmanager id="ScriptManager" runat="server">
        </asp:scriptmanager>
        <asp:updatepanel id="UpdatePanel" runat="server">
            <contenttemplate>
                <table>
                    <tr>
                        <td>
                            <asp:textbox id="txtImgUrl" runat="server"></asp:textbox>
                        </td>
                        <td>
                            <asp:button id="btnShow" runat="server" text="Show" onclick="btnShow_Click" />
                        </td>
                    </tr>
                    <tr>
                        <td>
                            <asp:label id="lblMessage" runat="server" visible="false"></asp:label>
                        </td>
                    </tr>
                </table>
                <br />
                <div>
                    <asp:image id="imgView" runat="server" alternatetext="Image Goes Here" visible="false" />
                </div>
            </contenttemplate>
        </asp:updatepanel>
    </div>
    </form>
</body>
</html>

and code behind like...

C#

protected void btnShow_Click(object sender, EventArgs e)
        {
            if (!string.IsNullOrEmpty(txtImgUrl.Text))
            {
                imgView.ImageUrl = txtImgUrl.Text;
                imgView.Visible = true;
            }
            else
            {
                lblMessage.Visible = true;
                lblMessage.Text = "Please add Url to text box";
            }
        }

and use image url like this...
