ZX Optimized Images


ZX Optimized Images is a free Zen Cart plugin for optimizing images. This plugin will automatically optimize your images, resize it to various dimensions and run it through resmush.it to provide the best possible optimization.

We DO offer professional installation service for the module, although you're most welcome to install it yourself. Installation is simple, although some basic code understanding is required.

Product images are usually the weak spot when it comes to page load time. If you have large high quality images, one single image can easily be 200-500 kB. Product listing pages can easily get to a few MBs because of the images which means it's slower to load.

This plugin will automatically resize your images to the sizes needed by your site, and will then run each of the resized image through one of the most popular image optimization services available.

Once the images are optimized, all optimized variants are saved to your server and are being loaded automatically based on the size needed. You can easily save several megabytes of data transfer when using optimized images. And, of course, the site will load significantly faster.

Let's not forget search engines will love it!

A detailed installation and usage manual is included with the plugin's zip file.

Before you proceed, make a backup of your STORE_ROOT/includes/functions/html_output.php file. Installation is done at your own risk.

Unzip the files from "files" directory to your computer. Rename "YOUR_ADMIN" folder to the name of your actual admin directory. Connect to your server via FTP. Now, upload your files using your FTP client (I recommend using Filezilla) to the store root. Be careful, the store root directory on the server is where your store is installed, not necessarily domain root.

One core file is overwritten (includes/functions/html_output.php) - there is one new block of code added to that file and is commented. If you made ANY changes to your html_output.php file, make sure you carefully merge the changes. You can use any code editor or find the differences using WinMerge or similar tools.

After you have finished uploading the files, go to your Zen Cart admin section and the plugin will auto-install. You'll find the new entries under Configuration->ZX Optimized Images.
