i ユーザーが画像をアップロードし、それらの画像がホーム画面に表示されるようにするサイトをセットアップしました。しかし、私は今壁にぶつかったので、ユーザーに画像をアップロードさせてから、その画像をフォルダーとデータベースに保存することにしましたが、画像がホーム画面に表示されるようにするにはどうすればよいですか。

 <?php

 // Connect to database

 $errmsg = "";
 if (! @mysql_connect("localhost","alfred1000351","*******")) {
 $errmsg = "Cannot connect to database";
     }
 @mysql_select_db("drp_2cgih5o233");



 $q = <<<CREATE
 create table pix (
 pid int primary key not null auto_increment,
 title text,
 imgdata longblob)
 CREATE;
 @mysql_query($q);

 // Insert any new image into database

  if ($_REQUEST[completed] == 1) {
  // Need to add - check for large upload. Otherwise the code
  // will just duplicate old file ;-)
 // ALSO - note that latest.img must be public write and in a
 // live appliaction should be in another (safe!) directory.
 move_uploaded_file($_FILES['imagefile']['tmp_name'],"latest.img");
 $instr = fopen("latest.img","rb");
 $image = addslashes(fread($instr,filesize("latest.img")));
 if (strlen($instr) < 149000) {
 mysql_query ("insert into pix (title, imgdata) values (\"".
 $_REQUEST[whatsit].
 "\", \"".
 $image.
 "\")");
 } else {
 $errmsg = "Too large!";
 }
 }

 // Find out about latest image

  $gotten = @mysql_query("select * from pix order by pid desc limit 1");
  if ($row = @mysql_fetch_assoc($gotten)) {
  $title = htmlspecialchars($row[title]);
  $bytes = $row[imgdata];
  } else {
  $errmsg = "There is no image in the database yet";
  $title = "no database image available";
  // Put up a picture of our training centre
  $instr = fopen("../wellimg/ctco.jpg","rb");
   $bytes = fread($instr,filesize("../wellimg/ctco.jpg"));
  }

 // If this is the image request, send out the image

if ($_REQUEST[gim] == 1) {
 header("Content-type: image/jpeg");
print $bytes;
exit ();
}
?>

<html><head>
<title>Upload an image to a database</title>
<body bgcolor=white><h2>Here's the latest picture</h2>
<font color=red><?= $errmsg ?></font>
<center><img src=?gim=1 width=144><br>
