Image Caching Increasing Image Size & Slowing Page?

Post by JoaniesGifts » Sat Sep 17, 2011 8:15 pm

Hi Guys,

I've stumbled across a strange problem today and apologies in advance if this is an obvious one - i'm not a developer and am learning opencart as i go for our shop.

I ran a speed test of my site using http://www.webpagetest.org/ and pointed it directly to my store page - http://www.joaniesgifts.co.uk/store/

I noticed from the results that it was taking a long time to load the 3 Nuvo Slider images on the homepage which was weird because i'd optimised them. I noticed that the jpgs were 70kb each instead of the original loaded size of under 25kb. I also noticed the cache version was being used and the images were low quality.

I looked in my cache/data folder and sure enough the image sizes seem larger than my originals even though they seem lower quality than the originals...

Very confused whats going on - is it because i enabled cache in my htaccess file? How can i tell opencart to use my original files?

Any help/tips would be appreciated as i dont even know where to start with this one

Joan
ps. - my slider extension was this one here - http://www.opencart.com/index.php?route ... on_id=1475

Meh, built into photoshop, no need for several programs

Anywhooo, Yes - disable the cache if you dont feel the need for it, there's nothing wrong with doing so at all

<?php
class Cache { 
	private $expire = 0; 
//cache stays forever but still will be present in /image/cache/data
	public function get($key) {
		return;	
			}

  	public function set($key, $value) {
    	return;
  	}
	
  	public function delete($key) {
		return;
  	}
}
?>

$new_image = 'cache/' . utf8_substr($filename, 0, utf8_strrpos($filename, '.')) . '-' . $width . 'x' . $height . '.' . $extension;

$new_image = '' . utf8_substr($filename, 0, utf8_strrpos($filename, '.')) . '-' . $width . 'x' . $height . '.' . $extension;
