hi

Can you try this function to convert to byte array

// C# to convert a string to a byte array.
public static byte[] StrToByteArray(string str)
{
System.Text.UTF8Encoding encoding=new System.Text.UTF8Encoding();
return encoding.GetBytes(str);
}
and pass the byte array for generating the image
public static Image CreateImage(byte[] imageData)
{
Image image;
using (MemoryStream inStream = new MemoryStream())
{
inStream.Write(imageData, 0, imageData.Length);

image = Bitmap.FromStream(inStream);
}

return image;
}

Hope it helps,thanks.
