HtmlInputImageTester Constructor (String, Tester)
            Create a tester for a server-side HTML control or a tag that's on a 
            page with multiple forms.  Use this constructor when the HTML tag you
            are testing has the "runat='server'" attribute.
            Also use this tester when using the non-default webform or HttpClient.
            
public HtmlInputImageTester(
   string aspId,   
Tester container);
Parameters
- aspId
 - The ID of the control to test (look in the
            page's ASP.NET source code for the ID).
 - container
 - A tester for the control's container.  
            (In the page's ASP.NET source code, look for the tag that the
            control is nested in.  That's probably the control's
            container.)  If testing a page with multiple forms or a non-default
            HttpClient, pass in the WebFormTester for the form this tag is within.
