resize script uses too much memory

[garydt]

I have this resize script: it works on smaller images but on larger images - over 2400 pixels wide, it uses too much memory

$filename = './uploads/'.$name;
	if(file_exists($filename)) 
	{
		$image		= imagecreatefromjpeg($filename); //unresized image
		$im_info	= getimagesize($filename); //unresized image
		$im_width	= $im_info[0];
		$im_height	= $im_info[1];
		$im_flag	= $im_info[2];

		//max height: 140px; max width: 140px
		if($im_width >= $im_height) {
			$im_divice	= $im_width / 140;
		}else {
			$im_divice	= $im_height / 140;
		}
		$thumb_width	= $im_width / $im_divice;
		$thumb_height	= $im_height / $im_divice;

		//create empty image
		$thumb	= imagecreatetruecolor($thumb_width, $thumb_height);
		//resize image
		imagecopyresampled($thumb, $image, 0, 0, 0, 0, $thumb_width, $thumb_height, $im_width, $im_height);

		if(imagejpeg($thumb, "thumbnails/".$name, 80)) { //image-resource, filename, quality
			return 1;
		}

		imagedestroy($thumb); //destroy temporary image-resource
		imagedestroy($image); //destroy temporary image-resource
	}

is there another way to resize images. My server only allocates 20M.

Thanks.

You should look at the php.net page for imagecreatefromjpeg. Many of the User Contributed Notes discuss this issue, and how to deal with it.
