Reduce File size

[proctk]

Hi the below code reduces the image at the same time it reduces the disk space the image uses.  It works excellent but I want to reduce the diskspace each file uses even more, but keep the image width and height the same

 

any ideas how to do this

 

thank you

// 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 = $HTTP_POST_FILES['file']['tmp_name'][$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/". $user_name."-".$HTTP_POST_FILES['file']['name'][$i];

imagejpeg($tmp,$filename,100);

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

$image_size = filesize($filename);
$image_name = $user_name."-".$HTTP_POST_FILES['file']['name'][$i];
$add_image = ("INSERT INTO image_files (image_name, image_size, user_id, create_date, album)
VALUES('$image_name', '$image_size', '$user_id', now(), '$album')");


$sql = mysql_query($add_image)or die("SQL Error: $add_image<br>" . mysql_error());

$otheralbum_cover = $user_name."-".$HTTP_POST_FILES['file']['name'][0];

mysql_query("UPDATE albumNames SET album_cover = '$otheralbum_cover' WHERE album= '$album' AND user_id = '$user_id'")or die ("Link Create Error:" .mysql_error());
}
endforeach;
//

In this line:

imagejpeg($tmp,$filename,100);

 

100 stands for the percentage of image quality. Reducing it to 80 or so will save you a nice amount of space, and you will have *almost* same quality.
