php+mysql 图象输入输出


我看了网上的例子~用了~发现图片进数据库没问题~但是关于输出部分总是报错~
代码如下
建库:
CREATE TABLE Images ( PicNum int NOT NULL AUTO_INCREMENT PRIMARY KEY, Image BLOB );
进库:<?php
     $Picture=$_POST[file];   //flie是 我那个图片上传页的表单的传递
         If($Picture != "none")
         { $PSize = filesize($Picture);
         $mysqlPicture = addslashes(fread(fopen($Picture, "r"), $PSize));
         mysql_connect("localhost","root","") or die("Unable to connect to SQL server");
         @mysql_select_db("mymg") or die("Unable to select database");
         mysql_query("INSERT INTO images (image) VALUES ('$mysqlPicture')") or die("Cant Perform Query"); }
         else
         { echo"You did not upload any picture"; }
         ?>
程序到这里都没问题~我用CMD看了下 数据库里也有东西.
输出:
<html>
<body>
<?php
mysql_connect($host,$username,$password) or die("Unable to connect to SQL server");
@mysql_select_db($db) or die("Unable to select database");
$result=mysql_query("SELECT * FROM Images") or die("Cant Perform Query");
While($row=mysql_fetch_object($result))
                { echo "<IMG SRC='Second.php ? PicNum=$row- > PicNum'/>"};!                 ?>
                 </body>
                 </html>
'Second.php:
          <?php
$result=mysql_query("SELECT * FROM Images WHERE PicNum=$PicNum") or die("Cant perform Query");
$row=mysql_fetch_object($result);

一直想在网上找个图片所略图程序，但是一直没有找到无变形的，一般都是对原图进行简单的缩放。
我想也许已经有了，只是我没有找到，所以没办法自己写了一个，其实也不是全是自己写的，只是
在已有的基础上改的！
源码如下：

<?php
/*
*版权说明：该版本是在“IEB_UPLOAD CLASS Ver 1.1”的基础上二次开发的，原程序对
*图片的裁剪将使图片变形、失真！本人在该程序的基础上进行了更改，用数据参数与原图片
*文件参数(主要是指宽和高)进行对比，得出比例值，先生成与原图片同比例缩放的图片，然
*后再以该中间图中心开始截取，从而获得缩略图，当然，图片会被裁剪，但是是最小限度的
*裁剪！
*程序设计：swin.wang  Email: php_in_china@yahoo.com.cn QQ:592298893
*
*该程序你可无限制使用，但请保留版权信息
×
×使用犯法：
*        $upfos = new ieb_upload('photo_file','./up_img'); photo_file 表单文件域名称，不要加$； ./up_img，上传位置

*        $old_file_fooder=$upfos -> getExt();
