case you browser knows to render the image from physical path, try open the html from another computer. — SilentTremor, Sep 15 '16 at 07:46

For local resources you have to use fully qualifed URLs prefixed by file:///. In your case your HTML the image tag should be:

<img src="file:///C:/Users/ingyadav/Desktop/icons/icons/logo_160.png" alt="Symphony Summit"/>

i tried it in your live demo but,still its not loading the image – aggy Sep 15 '16 at 09:28
The live demo runs on the EvoPdf server and cannot access local file from your computer. You have to download the library package from http://www.evopdf.com/download.aspx and try the demo on your computer. Let me know how this works for you – EvoPdf Sep 15 '16 at 09:49

That's easy, the source of your Image need be from http, if you have a console app and want to fix that you can transform the image into base64,

public string GetImage(string path)
{
  using (Image image = Image.FromFile(path))
    {                 
        using (MemoryStream m = new MemoryStream())
        {
            image.Save(m, image.RawFormat);
            byte[] imageBytes = m.ToArray();

            // Convert byte[] to Base64 String
            return Convert.ToBase64String(imageBytes);                
        }                  
    }
}

and

sb.Append("<img src=" + @"data:image/jpeg;base64," + GetImage(path) + "' />");

If you have a webapp, I strongly recommend using relative path, or a CDN path.

<img alt="Image with Full URL" src="http://www.domain.com/Images/Logo.jpg" />

or

<img alt="Image with Relative path" src="/Images/Logo.jpg" />

Actually,im converting the html to pdf and am sending the pdf as mail attachment. — aggy, Sep 15 '16 at 07:53
