I’ve been looking for PHP code to apply a Gaussian blur to images.

What I’ve done was like this:

<?php
$image = imagecreatefromjpeg('new.jpg'); 
imagefilter($image, IMG_FILTER_GAUSSIAN_BLUR);
imagejpeg($image, 'blur.jpeg');
imagedestroy($image);
?>

However the effect is very weak, and if I repeat the blur effect, it takes a very long time to process and the end result is still not that good.

I also used Timthumb , I always liked its simplicity, but it crops the image by default and its blurring effect is very weak.
