ใช้งาน imagecopyresized() ไม่ได้ครับ ผมต้องการให้แสดงรูปภาพจากฐานข้อมูล แต่จะโชว์เป็นขนาดเล็ก

<?php
// The file
$filename = 'test.jpg';

// Set a maximum height and width
$width = 200;
$height = 200;

// Content type
header('Content-type: image/jpeg');

// Get new dimensions
list($width_orig, $height_orig) = getimagesize($filename);

$ratio_orig = $width_orig/$height_orig;

if ($width/$height > $ratio_orig) {
   $width = $height*$ratio_orig;
} else {
   $height = $width/$ratio_orig;
}

// Resample
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);

// Output
imagejpeg($image_p, null, 100);
?> 

<?php
$file = $_GET['file'];

header('Content-type: image/jpeg');

list($width,$height) = getimagesize($file);
$thumb = imagecreatetruecolor("100","80");
$source = imagecreatefromjpeg($file);
imagecopyresized($thumb,$source,0,0,0,0,"100","80",$width,$height);
imagejpeg($thumb,"",80);

imagedestroy($source);
imagedestroy($thumb);
?>

<?php

$result1=mysql_query("SELECT * FROM tb_room WHERE id = '$id' ");
$row1=mysql_fetch_object($result1)  //select db

?>

<img src="resize.php?file=<?='../'.$row1->pic1;?>" /> //เรียกใช้
