image resize

[kproc]

Hi The below code takes an image and resizes it. The code runs kinda slow any ideas how to speed it up.

thank


// upload Images
if(isset($_POST['upLoadImages'])){
foreach ($_FILES['file']['tmp_name'] as $i => $val) :
if (is_uploaded_file($_FILES['file']['tmp_name'][$i])) {
// This is the temporary file created by PHP
$uploadedfile = $_FILES['file']['tmp_name'][$i];

// Create an Image from it so we can do the resize


$src = imagecreatefromjpeg($uploadedfile);

// Capture the original size of the uploaded image
list($width,$height)=getimagesize($uploadedfile);

// For our purposes, I have resized the image to be
// 600 pixels wide, and maintain the original aspect
// ratio. This prevents the image from being "stretched"
// or "squashed". If you prefer some max width other than
// 600, simply change the $newwidth variable
$newwidth=450;
$newheight=($height/$width)*450;
$tmp=imagecreatetruecolor($newwidth,$newheight);


// this line actually does the image resizing, copying from the original
// image into the $tmp image
imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height);

// now write the resized image to disk. I have assumed that you want the
// resized, uploaded image file to reside in the ./images subdirectory.
$filename = "../user_images/". $id."-".$HTTP_POST_FILES['file']['name'][$i];

imagejpeg($tmp,$filename,65);

imagedestroy($src);
imagedestroy($tmp); // NOTE: PHP will clean up the temp file it created when the request
// has completed.

The code runs kinda slow any ideas how to speed it up.Start with smaller images. That will save you both upload and processing time.

Thanks for the post. I'm trying to make uploading photos as easy as possible, I guess not many people have a 10.1 megapixal camera
