Hi, sorry if this is in the wrong section (if so please move it if neccessary)...

I am trying to create a PHP script to upload and resize images. I have read that I need need to use the djpeg, cjpeg and pnmscale UNIX utility programs from the libjpeg and libgr-progs library packages, but I have absolutely no idea how to install these packages on my server.

 

Server details:

Operating system Linux 

Kernel version 2.4.32-ow1

Machine Type i686

Apache version 1.3.37 (Unix)

PERL version 5.8.4 

PHP version 4.4.6

MySQL version 4.1.22-standard

cPanel Build 11.2.6-CURRENT 11817

Theme cPanel X v2.6.0 

 

Please could someone let me know what I need to do in order to find and install these packages.

Thanks very much!

Hi, Not sure you need all those packages! The below resizes images to 170 wide or high (depending portrait or landscape). You will also need the move_uploaded_file function (check out www.php.net for this).

 

 

<?
function resize_image($image_name) {
	$image_path = "/home/xyz/public_html/shots/" . $image_name;
	list($src_width, $src_height, $type, $attr) = getimagesize($image_path);
	if ($src_width > $src_height) {
		$new_w = 170;		
		$proportion = round( ( $src_width / $new_w ), 2 );
		$new_h = (int) ( $src_height / $proportion );
	} else {
		$new_h = 170;
		$proportion = round( ( $src_height / $new_h ), 2 );
		$new_w = (int) ( $src_width / $proportion );
	}
        $save_path = "/home/xyz/public_html/shots/thumbnail" . $image_name;


$src_img = imagecreatefromjpeg($image_path);
$dst_img = imagecreatetruecolor($new_w,$new_h);
imagecopyresized($dst_img,$src_img,0,0,0,0,$new_w,$new_h,imagesx($src_img),imagesy($src_img));
imagejpeg($dst_img, $save_path);
unlink($image_path);

  return 1; 
  }
?>

Yeah I realised that this was a bit of a long winded way of go about things, also thanks for the code it's helped quite a bit.
