how to save image in database

using (SqlConnection con = new SqlConnection(connectionString))
    {
    using (SqlCommand com = new SqlCommand("INSERT INTO myTable (myImage) VALUES (@IM)", con))
        {
        byte[] imageData = File.ReadAllBytes(@"F:\Temp\Picture.jpg");
        com.Parameters.AddWithValue("@IM", imageData);
        com.ExecuteNonQuery();
        }
    }

If you want to save an "image path" why do you use a column with an image datatype. Consider to change the column datatype to a string type (like VARCHAR) and save the path as a string. It's better for performance and for the storage capacity of your database.
