In C# how do I get the full URL from HTMLImgClass?

I am writing a program to download images from a web page.  I am able to download the images, but I would also like to log the full path of where it came from.

Below is the code that I have written.

            WebBrowser scrapeWebBrowser = new WebBrowser();

            scrapeWebBrowser.Navigate("http://yahoo.com");

            HTMLDocument objHtmlDocument = (HTMLDocument)scrapeWebBrowser.Document;

            foreach (HTMLImgClass imageElement in objHtmlDocument.images)
            {
                //HTMLImage
                WebClient client = new WebClient();
                string fileName = System.IO.Path.GetFileName(imageElement.href);
                client.DownloadFileAsync(new Uri(imageElement.href), System.IO.Path.Combine(@"L:\temp\imagedownload\", fileName));

                //How do I get the full url for imageElement?
            }

Is it possible to return the full URL from my declared variable imageElement?
