Other

• works on servers under Apache2, Nginx;
• does not work if you have the Pagespeed Module enabled on the server from Google;
• you cannot use the option to keep .jpg extension but serve .webp if you are using CloudFlare or a similar image caching system as webp images will be cached and served to non supporting browsers like Safari by CloudFlare;
• the module cannot be installed if another module already overrides the Link::getImageLink, Link::getCatImageLink, Link::getSupplierImageLink, Link::getManufacturerImageLink, Link::getStoreImageLink functions, if you have this situation, you can just delete the /override folder inside of the module archive and try the installation without it and follow the steps in the guide of each section, if you have nginx and are in this scenario, a few manual changes need to be done in the webserver config (there is a guide in the module webp section).
