Cart-Power Add-On: Image Optimization

Friends, we've updated our Image Optimization add-on!

image1.png

Image Optimization add-on improves page loading speed of the site, positively affects SEO and saves free server space without decreasing quality of images used for products, variations, blog and other CS-Cart objects.

How does it work?

- The add-on scans for images and analyzes their quality.

- You select 1 of 2 optimization services: resmush.it or shortpixel.com.

- You set preferred quality of optimized images and start optimization process.

When operation is complete, you get detailed stats on the results: number of optimized images, saved server space, etc.

Images, that were not optimized due to some issue are shown separately. You can optimize them once more with a separate feature.

The add-on also works with images used by third-party add-ons. Cron-script for auto optimization of new images is also available.

Add-on Features:

- Supported formats for images less than 5 MB - PNG, JPG, GIF, BMP, TIF, for other images - PNG, JPG, GIF;

- Displays optimization results: number of optimized images, saved server space, etc.;

- Ability to select optimization service: resmush.it or shortpixel.com;

- Ability to separate requests not to overload a server;

- Ability to select optimization quality;

- Optimization status of every image is saved into special logs;

- Ability to optimize only new images;

- Ability to separately repeat optimization for images not optimized due to various issues;

- Ability to browse all store images in admin panel at a single page;

- Ability to sort and search images by size, resolution, name, optimization status;

- Works with any object image: products, blog, characteristics, logos, etc.

- Ability to generate hash names for images to resolve issues with restricted symbols.

- Automation cron-script.

Hello,


Can you please post the link for storefront demo.

So we can compare the cs demo image and optimized images.


Great addon. Essential!

Regards

Nice one!

A couple of questions:

Is it possible to set a quality when using shortpixel? I tried their service but the image quality is not high enough when using lossy compression. The file sizes are extremely small which of course is good, but I'd rather have a bit bigger sized files and good quality - therefore i'm using Jpegmini at the moment who have found a good balance I think - honeslty I hardly see the difference between the original and a jpegmini file, while with shortpixel I see compression everywhere, unless I use PNG but than the filesize is too big.

Concerning resmush.it - I see quality can be chosen but do they also have a algorithm like shortpixel / jpegmini or is this simple old-fashioned JPG compression when using the paid version? Cause I tried the free version but it did not or hardly made my files smaller (free = lossless only).

Hello,

Thank you for your positive response.

Please, compare images of the TomTom GO LIVE Top Gear edition product.

Unfortunately, there are only a few images in the CS-Cart demo to see the significant difference in the file size after the optimization.

Thank you.

As for Shortpixel.com, unfortunately, there is no opportunity to choose the compression level. The

Resmush.it is a FREE service, max file size = 2Mb. For files more than 2Mb we offer to use shortpixel. This tool is based on several well-known algorithms such as pngquant, jpegoptim, optipng. It allows to reduced until 70%-80% the size of uploaded pictures.

Thank you.

Aha - but resmush.it also offers a paid service, with a special lossy compression. So the plugin can not use this?

As for shortpixel, I am actually in touch with them about their quality. If they improve their quality or add another quality option you have a fantastic plugin here.

Dear friends!

We are glad to introduce you our new Image Optimization add-on that allows to compress images using the external services Resmush.it and Shortpixel.com within store administration panel.


I suppose the best advertisement of your add-on would be the stats: total image size before optimization vs total images size after optimization.

I tested an image (photo with text) and it went from 520kb (JPG 99) to 78kb. Image quality was still very respectable, comparable to about jpg 85.

This add-on is perfect because you can just upload high res images, so employees without any knowledge of optimizing images can also upload without worries.

I'm actually in touch with Shortpixel, they will probably add a super HQ setting so that the quality stays very high (with naturally slightly larger filesize).

I can share the images later if anyone is interested.

Dear colleagues,

We have added examples of the optimized images into the general description of the add-on.

Dear friends,

We are glad to inform you that the issue with the product images display has been fixed.

Thank you.

I see bright future for this addon :stuck_out_tongue:

Dear Friends,

We are glad to inform you that we have extended the functionality of the Image Optimization add-on. Now there is a separate page with all store images is available. These images can be not only optimized, but also sorted, searched, uploaded, downloaded and even converted in some cases.

Please, see details on the official product page.

Thank you.

Dear friends!

Cart-Power: would you consider adding serverside image compression tools to this addon? It is possible to achieve similar results as Remush.it, Shortpixel.com, jpegmini.com, etc. using image libraries such as imagemagick. Here is an in-depth article on the subject:
