Decoding Base64 Image

Use Convert.FromBase64String to get a byte[] representing the image binary.

You can then save the resulting byte[] into a file.

Byte[] bitmapData = Convert.FromBase64String(FixBase64ForImage(ImageText));
System.IO.MemoryStream streamBitmap = new System.IO.MemoryStream(bitmapData);
Bitmap bitImage = new Bitmap((Bitmap)Image.FromStream(streamBitmap));

public string FixBase64ForImage(string Image) { 
    System.Text.StringBuilder sbText = new System.Text.StringBuilder(Image,Image.Length);
    sbText.Replace("\r\n", String.Empty); sbText.Replace(" ", String.Empty); 
    return sbText.ToString(); 
}

Scrape the embedded image into a string. Using WebClient is probably your best bet. Convert the base64 string to a byte array using Convert.FromBase64String(). Use a MemoryStream and Image.FromStream() to reconstitute an image object.
