It turns out that I'm trying to save an image on my computer, but I get the following error:

  

A generic error occurred in GDI +.

The code I have is the following: 

    private static void StartBrowser(string source)
    {
        var th = new Thread(() =>
        {
            var webBrowser = new WebBrowser();
            webBrowser.ScrollBarsEnabled = false;
            webBrowser.DocumentCompleted +=
                webBrowser_DocumentCompleted;
            webBrowser.DocumentText = source;
            Application.Run();
        });
        th.SetApartmentState(ApartmentState.STA);
        th.Start();
    }

    static void
        webBrowser_DocumentCompleted(
        object sender,
        WebBrowserDocumentCompletedEventArgs e)
    {
        var webBrowser = (WebBrowser)sender;
        using (Bitmap bitmap =
            new Bitmap(
                webBrowser.Width,
                webBrowser.Height))
        {
            webBrowser
                .DrawToBitmap(
                bitmap,
                new System.Drawing
                    .Rectangle(0, 0, bitmap.Width, bitmap.Height));


            bitmap.Save(@"c:\imagen.png",
                System.Drawing.Imaging.ImageFormat.Png);
        }
    }

    private void button1_Click(object sender, EventArgs e)
    {
        var source = @"
    <!DOCTYPE html>
    <html>
        <body>
            <p>An image from W3Schools:</p>
            <img 
                src=""http://www.w3schools.com/images/w3schools_green.jpg"" 
                alt=""W3Schools.com"" 
                width=""104"" 
                height=""142"">
        </body>
    </html>";
        StartBrowser(source);
    }

The error comes out just this part: 

bitmap.Save(@"c:\imagen.png",System.Drawing.Imaging.ImageFormat.Png);

I hope I can count on your help.

In this case, the problem is that you do not have the necessary permissions to write directly to the drive C:\ : c:\imagen.png .

The solution is to change the path to a directory to which you do have access in writing.
