please check my code

System.Drawing.Image imag = System.Drawing.Image.FromStream(Fileupload1.PostedFile.InputStream);

cmd.Parameters.Add("@image", SqlDbType.Image, 0).Value = ConvertImageToByteArray(imag, System.Drawing.Imaging.ImageFormat.Jpeg);

private byte[] ConvertImageToByteArray(System.Drawing.Image imageToConvert, System.Drawing.Imaging.ImageFormat formatOfImage)
{
byte[] Ret;
try
{
using (MemoryStream ms = new MemoryStream())
{
imageToConvert.Save(ms, formatOfImage);
Ret = ms.ToArray();
}
}
catch (Exception) { throw; }
return Ret;
}

In this code i have one fileupload control.
I want that then user not select their photo then default photo (Avatar.jpg)file save in the database.

I dunno what the other guy is saying, but you can't set the path to a file upload control, because if you could, you could hide one on your page with the path to a system file and hack someone's system that way. You can't set it in js or in your html.

So, if they don't select a photo, push in your avatar. That means the upload control is blank. If it had the name of the default image, that file would need to exist on the client
