For the image optimization, do we need running optimization all the time when the new image is uploaded?
According to the extension’s functionality, all newly uploaded images will be optimized automatically. Make sure to enable the following setting in Stores > Configuration > Amasty Extensions > Image Optimizer > Automatic Optimization of the Newly Uploaded Images:
Once done, kindly navigate to the Amasty > Image Optimizer > Image Folder Optimization Settings and enable Automatically Optimize Newly Uploaded Images in Folder setting for the pattern created:
Additionally, the Premium version of the extension provides the options to set up an optimization schedule in Stores > Configuration > Amasty Extensions > Image Optimizer > Automatic Image Optimization:
Since v.3.6.0 Premium version of the module introduces Automatically Optimize Existing Images feature, enabling automatic optimization of existing images based on pattern settings (Note: the functionality is available as a part of an active product subscription or support subscription. You can find the 'amasty/module-optimizer-premium-subscription-functionality' package for installing in composer suggest.)
Since v. 3.8.0 Pro and Premium versions of the module introduce a new Image Optimization Strategy > Visited Pages that automatically optimizes images based on the visited frontend pages. (Note: the functionality is available as a part of an active product subscription or support subscription. You can find the 'amasty/module-image-optimizer-visited-pages' package for installing in composer suggest.)Please note, if 'Visited Pages' option is selected, manual optimization based on folders will no longer work.
