1、给xxx_category表增加一个varchar类型的category_img字段,用来存储上传的图片路径字符串
alter table  `ecs_category` add cat_img varchar(255)
alter table  `ecs_category` add cat_img_link varchar(255) 
2、网站目录/admin/category.php
(1)查找
    $exc = new exchange($ecs->table("category"), $db, 'cat_id', 'cat_name');
这一语句,并在该语句下面大约行20增加:
    include_once(ROOT_PATH . '/includes/cls_image.php');
    $image = new cls_image($_CFG['bgcolor']);
    // 最大上传文件大小
    $php_maxsize = ini_get('upload_max_filesize');
    $htm_maxsize = '2M';
(2)查找
    $cat['cat_recommend']  = !empty($_POST['cat_recommend'])  ? $_POST['cat_recommend'] : array();并在该语句下面大约行111增加:
$cat['cat_img']      = '';  //自定义上传分类图
    $cat['cat_img_link']  = !empty($_POST['cat_img_link'])    ? trim($_POST['cat_img_link']) : '';
    //检查是否有上传分类图片
    if (isset($_FILES['cat_img']))
    {
      //如果有错误
      if($_FILES['cat_img']['error'])
      {
      if ($_FILES['cat_img']['error'] == 0)
      {
        if (!$image->check_img_type($_FILES['cat_img']['type']))
        {
        sys_msg("上传的分类图类型无效", 1, array(), false);
        }
      }
      elseif ($_FILES['cat_img']['error'] == 1)
      {
        sys_msg(sprintf("上传的分类图超过了大小", $php_maxsize), 1, array(), false);
      }
      elseif ($_FILES['cat_img']['error'] == 2)
      {
        sys_msg(sprintf("上传的分类图超过了大小", $htm_maxsize), 1, array(), false);
      }
      }
      else  //没有错误检查是否存在temp目录
      {
      if ($_FILES['cat_img']['tmp_name'] != 'none')
      {
        if (!$image->check_img_type($_FILES['cat_img']['type']))
        {
        sys_msg('无效的分类图片', 1, array(), false);
        }
      }
      }
      //如果上传了分类图,则进行相应处理
      if ($_FILES['cat_img']['tmp_name'] != '' && $_FILES['cat_img']['tmp_name'] != 'none')
      {
      $catimg  = $image->upload_image($_FILES['cat_img']); // 上传的商品色彩图
      if ($catimg === false)
      {
        sys_msg($image->error_msg(), 1, array(), false);
      }
      else
      {
        $cat['cat_img'] = $catimg;
      }
      } 
    }
(3)查找下一段
    $cat['cat_recommend']  = !empty($_POST['cat_recommend'])  ? $_POST['cat_recommend'] : array();
并在该语句下面大约行323增加:
$issave_catimg      = !empty($_POST['issave_catimg']) ? intval($_POST['issave_catimg']) : 1;
    $cat['cat_img_link']  = !empty($_POST['cat_img_link'])    ? trim($_POST['cat_img_link']) : '';

            //检查是否有上传分类图片
            if (isset($_FILES['cat_img']))
            {
                      //如果有错误
                      if($_FILES['cat_img']['error'])
                      {
                                if ($_FILES['cat_img']['error'] == 0)
                                {
                                        if (!$image->check_img_type($_FILES['cat_img']['type']))
                                        {
                                                  sys_msg("上传的分类图类型无效", 1, array(), false);
                                        }
                                }
                                elseif ($_FILES['cat_img']['error'] == 1)
                                {
                                        sys_msg(sprintf("上传的分类图超过了大小", $php_maxsize), 1, array(), false);
                                }
                                elseif ($_FILES['cat_img']['error'] == 2)
                                {
                                        sys_msg(sprintf("上传的分类图超过了大小", $htm_maxsize), 1, array(), false);
                                }
                      }
                      else  //没有错误检查是否存在temp目录
                      {
                                if ($_FILES['cat_img']['tmp_name'] != 'none')
                                {
                                        if (!$image->check_img_type($_FILES['cat_img']['type']))
                                        {
                                                  sys_msg('无效的分类图片', 1, array(), false);
                                        }
                                }
                      }

                      //如果上传了分类图,则进行相应处理
                      if ($_FILES['cat_img']['tmp_name'] != '' && $_FILES['cat_img']['tmp_name'] != 'none')
                      {
                                $catimg  = $image->upload_image($_FILES['cat_img']); // 上传的商品色彩图
                                if ($catimg === false)
                                {
                                        sys_msg($image->error_msg(), 1, array(), false);
                                }
                                else
                                {
                                        $cat['cat_img'] = $catimg;
                                }

                                //检查是否存在上传的分类图,如果有则删除
                                $cat_img = $db->getOne('SELECT cat_img FROM ' .$ecs->table('category'). " WHERE cat_id='$cat_id'");
                                if($cat_img != '' && is_file('../' . $cat_img))
                                {
                                        @unlink('../' . $cat_img);
                                }        
                      }
            }

            if($issave_catimg == 2)
            {
                      //检查是否存在上传的分类图,如果有则删除
                      $cat_img = $db->getOne('SELECT cat_img FROM ' .$ecs->table('category'). " WHERE cat_id='$cat_id'");
                      if($cat_img != '' && is_file('../' . $cat_img))
                      {
                                @unlink('../' . $cat_img);
                                $cat['cat_img'] = '';
                      }
            }
(4)查找
    if ($cat_count == 0 && $goods_count == 0)  
    {并在该行下面大约691增加:
    //检查是否存在上传的分类图,如果有则删除
                  $cat_img = $db->getOne('SELECT cat_img FROM ' .$ecs->table('category'). " WHERE cat_id='$cat_id'");
                  if($cat_img != '' && is_file('../' . $cat_img))
                  {
                            @unlink('../' . $cat_img);
                  }
三、网站目录/category.php
(1)查找$smarty->display('category.dwt', $cache_id);在该语句上面大约行396增加:
    //获取自定义分类增加的信息
    $cat_id = intval($_REQUEST['id']);
    $sql = "SELECT * FROM " .$GLOBALS['ecs']->table('category'). " WHERE cat_id='$cat_id' LIMIT 1";
    $cat_info  = $GLOBALS['db']->getRow($sql);
    if($cat_info)
    {
    $cat_img      = $cat_info['cat_img'];
    $cat_img_link = $cat_info['cat_img_link'];
    $smarty->assign('cat_img', $cat_img);
    $smarty->assign('cat_img_link', $cat_img_link);
    }
四、打开admin/templates/category_info.htm
