Try this method. It should work when field when you want to store image is of type bytea. First it creates byte[] for image. Then it saves it DB using IDataParameter of type binary.

C#

public static void PerisitImage(string path, IDbConnection connection)
    {
        using (var command = connection.CreateCommand ())
        {
            Image img = Image.FromFile (path);
            MemoryStream tmpStream = new MemoryStream();
            img.Save (tmpStream, ImageFormat.Png); // change to other format
            tmpStream.Seek (0, SeekOrigin.Begin);
            byte[] imgBytes = new byte[MAX_IMG_SIZE];
            tmpStream.Read (imgBytes, 0, MAX_IMG_SIZE);

            command.CommandText = "INSERT INTO images(payload) VALUES (:payload)";
            IDataParameter par = command.CreateParameter();
            par.ParameterName = "payload";
            par.DbType = DbType.Binary;
            par.Value = imgBytes;
            command.Parameters.Add(par);
            command.ExecuteNonQuery ();
        }
    }

//use this method to open an image

public Byte[] StoreImageTODB()
{
FileStream fs = new FileStream(path,FileMode.Open,FileAccess.Read);
// path is the actual path to the image
Byte[] byteimagedata = new Byte[fs.Length];
fs.Read(byteimagedata,0,byteimagedata.Length);
fs.Close();
return byteimagedata;
}

// Then you can call it where you are going to store the image to the database.

public void InsertImage()
{
bool status;
Byte[] imagedata = StoreImageTODB();// call above method and get image to Byte array
string ID = "01"; // just as an example
status=dba.Insert_Image(ID,imagedata); // dba is the object of the DBACCESS class

if(status)
messageBox.Show("Success");

}

// In DBACCESS class you can catch those parameters

public bool InsertNewEmp(string ID,Byte[] image) // insret new data
{
bool status = false;
try
{

if (conn.State.ToString() == "Closed")
{
conn.Open();
}

SqlCommand newCmd = conn.CreateCommand();

newCmd.Connection = conn;
newCmd.CommandType = CommandType.Text;
newCmd.CommandText = "insert into ImageDetails(ID,ID_Image) values('" +ID + "',@Image)";
SqlParameter prm = new SqlParameter("@Image", SqlDbType.VarBinary, image.Length, ParameterDirection.Input, false,0, 0, null, DataRowVersion.Current, image);
newCmd.Parameters.Add(prm);

newCmd.ExecuteNonQuery();

status = true;

}
catch (Exception ex)
{
MessageBox.Show("Your Database connection has an error !!!", "Error", MessageBoxButtons.OK, MessageBoxIcon.Warning);
}
return status;
}
