Optimized Thumbnails

Changed Google Recommendations since May 2019

Our plugin implements the image optimization method Google recommended until 2019. In the new version of the image optimization article new methods like the JPEG encoder guetzli developed by google are recommended. Shopware supports guetzli in the newer versions. If your server doesn't support guetzli the plugin can still be of use for you but we recommend to check if the plugin is the right solution for you.

Reduce Imagesize

Online shops work with many pictures. Customers should be able to see products as detailed as possible, banners and seals should arouse emotions and trust. Pictures are the decisive factor for the loading time of your shop. To make sure that they look good and still do not slow down the pagespeed, it's important that they are optimally compressed.

Improve Google Pagespeed

According to studies, the loading time of a page has a direct influence on the bounce rate of websites. Google therefore is using page speed on mobile devices as a ranking factor in organic Google search since July 2018.

Think mobile

For customers who visit your shop with mobile devices, the amount of data transferred per page view is particularly important. Those who have a bad internet connection on their mobile phone will not have enough patience to wait until several big images have been loaded. Especially here the loading time is very important and one of the decisive factors for the conversion rate.

Product images without unnecessary artifacts

Because of a bug in the PHP library GdLib, most thumbnail images created by Shopware contain disturbance pixels - so-called artifacts - on the white areas. On high contrast monitors, this is seen as a gray "border". By generating the images with the Linux program ImageMagick we avoid the problem.

Less CPU load, save CO², help polar bears

By using a native Linux program to create the thumbnails, which allows us to change the image size and compress it in one step, we speed up the process, save computing time and thus relieve your server. Maybe we can reduce energy comsumption in  the data centers of the hosting providers and help to save polar bears.

In order to use the plugin effectively, settings must be made in the Media Manager and thumbnails must be regenerated. Please follow the installation instructions. If you are unsure about how to use the plugin, please contact us.

läuft reibungslos

21 May 2019

Super-Schnelle Rückmeldung vom Entwickler. Die Generierung der Thumbnails läuft reibungslos. Ein Schnelligkeitstest steht zwar noch aus, da ich auf das Aufwärmen vom Cache warte. Bin nach Durchsicht auf aber zuversichtlich und vergebe 5 Sterne.


Alles prima

Installation manual

For the plugin to work, it is imperative that your shop runs on a Linux server on which the ImageMagick program is installed.  

For common shopware hosting partners this is usually fulfilled. On root servers it may be necessary to install the program yourself. 

If you are unsure, contact your provider before purchasing the plugin.   If the requirements are met, the plugin replaces the Shopware internal mechanism for creating thumbnails. If you upload new images or regenerate the thumbnails for an album, the shop will use ImageMagick to generate the thumbnail images and will compress the image at the same time.  

For the normal (re)creation of thumbnails, the JPEG quality set in the Media Manager in the album applies.  

However, Google recommends a quality of 85. If a quality of more than 85 is set in an album, the plugin overwrites this value and calculates with a quality of 85.  

If you need pictures in higher quality you can deactivate this in the plugin settings - then the values set in the albums in the media manager apply.  

The JPEG quality, which you can configure in the plugin settings, only takes effect if you optimize images afterwards with the Shopware console.  

To recompress the already existing thumbnail images you have to recreate the thumbails once. This can be done either via the Media Manager in the backend or via the Shopware console.
