仅供参考：

   private void FormChart_Load(object sender, EventArgs e)
        {
            //生成DataTable
            DataTable dta = new DataTable("Test");
            dta.Columns.Add("ID", typeof(System.Int32));
            dta.Columns.Add("Name", typeof(System.String));
            dta.Columns.Add("Address", typeof(System.String));
            dta.Columns.Add("Image",typeof(System.Byte[]));
            //图片路径
            string filePath = AppDomain.CurrentDomain.BaseDirectory + "\\image\\Status_OK.png";
            Image img = new Bitmap(filePath);           
            byte[] imgBytes = ImageToBytes(img);
 
            dta.Rows.Add(new object[] { 1, "张三", "北京市海淀区" , imgBytes });
            dta.Rows.Add(new object[] { 1, "李四", "北京市朝阳区", imgBytes });
            dta.Rows.Add(new object[] { 1, "王五", "北京市东城区", imgBytes });
            dta.Rows.Add(new object[] { 1, "赵六", "北京市西城区", imgBytes });
            dta.AcceptChanges();
 
            //设置行高
            gv.RowHeight = 32;
           //格式化图片列
            RepositoryItemPictureEdit pic = new RepositoryItemPictureEdit();
            //图片居中
            pic.PictureAlignment = ContentAlignment.MiddleCenter;
            //图片垂直拉伸
            pic.SizeMode = DevExpress.XtraEditors.Controls.PictureSizeMode.Zoom;
            gv.Columns["Image"].ColumnEdit = pic;
            
            //绑定
            grid.DataSource = dta;
        }
        
        /// <summary>
        /// Image 转成 Byte[]
        /// </summary>
        /// <param name="image">图片</param>
        /// <returns></returns>
        public static byte[] ImageToBytes(Image image)
        {
            ImageFormat format = image.RawFormat;
            using (MemoryStream ms = new MemoryStream())
            {
                if (format.Equals(ImageFormat.Jpeg))
                {
                    image.Save(ms, ImageFormat.Jpeg);
                }
                else if (format.Equals(ImageFormat.Png))
                {
                    image.Save(ms, ImageFormat.Png);
                }
                else if (format.Equals(ImageFormat.Bmp))
                {
                    image.Save(ms, ImageFormat.Bmp);
                }
                else if (format.Equals(ImageFormat.Gif))
                {
                    image.Save(ms, ImageFormat.Gif);
                }
                else if (format.Equals(ImageFormat.Icon))
                {
                    image.Save(ms, ImageFormat.Icon);
                }
                byte[] buffer = new byte[ms.Length];
                //Image.Save()会改变MemoryStream的Position，需要重新Seek到Begin
                ms.Seek(0, SeekOrigin.Begin);
                ms.Read(buffer, 0, buffer.Length);
                return buffer;
            }
        }
