减少将要存储在SQL中的图像大小的最佳方法是什么

Question

您好我的想法是将照片存储在SQL数据库中，我想知道如何减少图像的大小，以便它在数据库中占用太多空间。我使用SQL数据库的替代方法或？

这是我用来转换和插入图片的当前代码。

    byte[] img = null;
    int x,i;
    private void button4_Click(object sender, EventArgs e)
    {

        FileStream fs = new FileStream(imgloc,FileMode.Open, FileAccess.Read);
        BinaryReader reader = new BinaryReader(fs);
        img = reader.ReadBytes((int)fs.Length);

        try
        {
            SqlCommand command = new SqlCommand("INSERT INTO Staff(id,Username,Password,Image) VALUES(@ID,'Nasar',0,@nasar)",connection);
            command.Parameters.Add(new SqlParameter("@nasar", img));
            command.Parameters.Add("@ID",i);

            connection.Open();
            command.ExecuteNonQuery();

        }
        catch(Exception ex)
        {
            MessageBox.Show("An Error has accured! Please send this message to support (" + ex.Message + ")");
            if(ex != null)
            {
                x = 1;
            }
        }
        finally
        {
            if (connection != null)
            {
                connection.Close();
            }

            if (x == 0)
            {
                MessageBox.Show("Image has been recorded");
                i++;
            }


        }
    }
