I wrote this some time ago for a car sales dept, so they could upload large
photos without resizing them. It ruins the quality though.
This is just the resize bit, but it may help you if you adapt it.
If the photo is larger than 600x600, it resizes them.
<?php
$myphoto = $_FILES['filename']['name'];
if (substr($myphoto, -3) == "jpg") {
$addfile = move_uploaded_file($_FILES['filename']['tmp_name'],$myphoto);
// resize photo if necessary
define('MAXWIDTH',600);
define('MAXHEIGHT',600);
$img = imagecreatefromjpeg($myphoto);
$width = imagesx($img);
$height = imagesy($img);
$scale = min(MAXWIDTH/$width,MAXHEIGHT/$height);
if ($scale < 1) {
$new_width = floor($width * $scale);
$new_height = floor($height * $scale);
$new_img = imagecreatetruecolor($new_width,$new_height);
imagecopyresized($new_img,$img,0,0,0,0,$new_width,$new_height,$width,$height);
imagedestroy($img);
imagejpeg($new_img, $myphoto);
}
// resize end
$goto = $_SERVER['PHP_SELF']."?addfile=yes";
header("Location: $goto");
exit;
}
?>
Regards, Bob.
