Casting mshtml.IHTMLImgElement to mshtml.IHTMLElementRender does not work with E_NOINTERFACE

I have a C # .NET 4 WinForms application (using MSHTML 7) that launches new ones and connects to existing instances of IE 10. It iterates through all the images and loads them for management. This approach is time consuming and redundant since the image is already loaded by IE.

I searched everywhere and only a few forums discuss the topic, but all of them can drop mshtml.IHTMLImgElement objects in mshtml.IHTMLElementRender (albeit in C ++ code).

Unable to cast COM object of type 'mshtml.HTMLImgClass' to interface type 'mshtml.IHTMLElementRender'.
This operation failed because the QueryInterface call on the COM component for the interface with IID '{3050F669-98B5-11CF-BB82-00AA00BDCE0B}' failed due to the following error:
No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

The aim of the course is to gain access to the full image, so alternative approaches are welcome. Here is the code that throws the exception above.

public static void Main (string [] args)
{
    mshtml.HTMLDocument document = null;
    SHDocVw.InternetExplorer explorer = null;
    System.IntPtr hdc = System.IntPtr.Zero;
    mshtml.IHTMLElementRender render = null;
    mshtml._RemotableHandle handle = default(mshtml._RemotableHandle);

    try
    {
        explorer = new SHDocVw.InternetExplorer();
        explorer.Visible = true;

        try
        {
            explorer.Navigate("http://www.google.com/ncr");

            while (explorer.Busy)
            {
                // Striped events for SO example.
                System.Threading.Thread.Sleep(100);
            }

            document = (mshtml.HTMLDocument) explorer.Document;

            foreach (mshtml.IHTMLImgElement image in document.images)
            {
                Console.WriteLine();

                if ((image.width > 0) && (image.height > 0))
                {
                    // The following [if] will return false if uncommented.
                    //if (image.GetType().GetInterfaces().ToList().Contains(typeof(mshtml.IHTMLElementRender)))
                    {
                        using (Bitmap bitmap = new Bitmap(image.width, image.height))
                        {
                            using (Graphics graphics = Graphics.FromImage(bitmap))
                            {
                                hdc = graphics.GetHdc();
                                handle.fContext = hdc.ToInt32();
                                render = (mshtml.IHTMLElementRender) image; // Causes the exception.
                                //handle = (mshtml._RemotableHandle) Marshal.PtrToStructure(hdc, typeof(mshtml._RemotableHandle));
                                render.DrawToDC(ref handle);
                                graphics.ReleaseHdc(hdc);

                                // Process image here.

                                Console.Write("Press any key to continue...");
                                Console.ReadKey();
                            }
                        }
                    }
                }
            }
        }
        catch (System.Exception e)
        {
            Console.WriteLine(e.Message);
            Console.WriteLine("Stack Trace: " + e.StackTrace);
        }

        explorer.Quit();
    }
    catch (System.Exception e)
    {
        Console.WriteLine(e.Message);
        Console.WriteLine("Stack Trace: " + e.StackTrace);
    }
    finally
    {
    }

#if (DEBUG)
        Console.WriteLine();
        Console.Write("Press any key to continue...");
        Console.ReadKey();
#endif
}
