provides a free version which has a watermark on all the images or it costs about $100 for the full version which doesn't have the watermark. It comes with C# and VB .NET sample code and is easy enough to install and use.

 

also provides some useful functions for parsing HTML.

 

if you decide to truly implement this your self in asp.net you can use WebBrowser component. Here is a little tutorial on that:

is there any free software available

 

It is not easy to generate the thumb images. It is better to use third party API, DomainTools.com provide this API. Try it.

 

Hello,

You can create in APS.NET but for classic asp you required component.
You can also create website thumb easily in PHP.
Furthermore many website provides this type of services below is one of them search in google you will fine it easily

Here is code for C#: Generate WebPage Thumbmail Screenshot Image

//Codes

public Bitmap GenerateScreenshot(string url)
{
    // This method gets a screenshot of the webpage
    // rendered at its full size (height and width)
    return GenerateScreenshot(url, -1, -1);
}

public Bitmap GenerateScreenshot(string url, int width, int height)
{
    // Load the webpage into a WebBrowser control
    WebBrowser wb = new WebBrowser();
    wb.ScrollBarsEnabled = false;
    wb.ScriptErrorsSuppressed = true;
    wb.Navigate(url);
    while (wb.ReadyState != WebBrowserReadyState.Complete) { Application.DoEvents(); }


    // Set the size of the WebBrowser control
    wb.Width = width;
    wb.Height = height;

    if (width == -1)
    {
        // Take Screenshot of the web pages full width
        wb.Width = wb.Document.Body.ScrollRectangle.Width;
    }

    if (height == -1)
    {
        // Take Screenshot of the web pages full height
        wb.Height = wb.Document.Body.ScrollRectangle.Height;
    }

    // Get a Bitmap representation of the webpage as it's rendered in the WebBrowser control
    Bitmap bitmap = new Bitmap(wb.Width, wb.Height);
    wb.DrawToBitmap(bitmap, new Rectangle(0, 0, wb.Width, wb.Height));
    wb.Dispose();

    return bitmap;
} 

//Usage
