Code:

                   foreach (GeckoHtmlElement imgelement in geckoWebBrowser1.Document.GetElementsByTagName("div"))
                    {
                        if (imgelement.GetAttribute("id")=="adcopy-puzzle-image")
                        {
                            GeckoImageElement ourimgage = (GeckoImageElement)imgelement;
                           Image ourimg = (System.Drawing.Bitmap)System.Drawing.Image.FromStream(new System.IO.MemoryStream(Gecko.Utils.SaveImageElement.ConvertGeckoImageElementToPng(geckoWebBrowser1, ourimgage, 0, 0, ourimgage.OffsetWidth, ourimgage.OffsetHeight)));
                        }
                    }

This way you should get your image in 'ourimg' var. You can directly load it into picture box or save into disk.

Has this been fixed?
I will be more than happy to close this thread on your command.

I found this ... working good

public void getsolvemedia(int a, int b)
{

Bitmap bmp = new Bitmap(CreateImage(wb));
Rectangle cropRect = new Rectangle(a, b, 307, 157);
bmp.Save("full.png");
bmp = bmp.Clone(cropRect, bmp.PixelFormat);
Image img = bmp;
img = resizeImage(img, new Size(153, 79));
img.Save("captcha.png");
picture.Image = img;
GeckoInputElement answer = new GeckoInputElement(wb.Document.GetElementsByName("a dcopy_response")[0].DomObject);
answer.Value = captcha;
if (captcha.Length >= 2)
{
GeckoButtonElement sub = new GeckoButtonElement(wb.Document.GetElementsByClassN ame("btn btn-warning")[0].DomObject);
sub.Click();
}
}
public static Image resizeImage(Image imgToResize, Size size)
{
return new Bitmap(imgToResize, size);
}
private Image CreateImage(GeckoWebBrowser browser)
{
var w = wb.Document.ActiveElement.ScrollWidth;
var h = wb.Document.ActiveElement.ScrollHeight;

var creator = new ImageCreator(browser);
byte[] imageBytes = creator.CanvasGetPngImage((uint)w, (uint)h);
using (var stream = new MemoryStream(imageBytes))
{
return Image.FromStream(stream);
}
}
public Point GetOffset2(GeckoHtmlElement el)
{
Point pos = new Point(el.OffsetLeft, el.OffsetTop);
GeckoHtmlElement tempEl = el.OffsetParent;
while (tempEl != null)
{
pos.X += tempEl.OffsetLeft;
pos.Y += tempEl.OffsetTop;
tempEl = tempEl.OffsetParent;
}
return pos;
}
var point = GetOffset2(wb.Document.GetHtmlElementById("adcopy-outer"));
var x = point.X;
var y = point.Y;
getsolvemedia(x, y);

or easier methode

using Gecko.Utils;

Point GetScreenCordinates(GeckoHtmlElement obj)
{
Point p = new Point();

try
{
p.X = obj.OffsetLeft;
p.Y = obj.OffsetTop;

GeckoHtmlElement _Parent = obj;
while ((_Parent = _Parent.OffsetParent) != null)
{
p.X += _Parent.OffsetLeft;
p.Y += _Parent.OffsetTop;
}
}
catch { }

return p;
}

private Bitmap GetElementAsImage(GeckoHtmlElement input)
{
Point cords = GetScreenCordinates(input);
return ActiveBrowser.GetBitmap((uint)cords.X, (uint)cords.Y, (uint)input.ClientWidth, (uint)input.ClientHeight);
}
GetElementAsImage((GeckoHtmlElement)ActiveBrowser. Document.GetElementById("adcopy-outer"));
