The Avada theme generates image sizes for the most important areas, so that images of fitting sizes can be loaded on the frontend instead of always loading the full image size. It may seem like a lot of images, but this reduces loading time considerably on the front end for your viewers. We feel the performance increase is well worth the extra image files. If you would like to change this to your needs, please read the information below.
How To Reduce Image Size Generation
Step 1 – Go to the Avada > includes file path and open the class-avada-init.php.
Step 2 – Inside the class-avada-init.php file, locate the add_image_size calls there. Comment out any size you don’t want to include by adding a double backslash ( // ) before them.
Step 3 – Once finished, don’t forget to save your changes.
Step 4 – Run the Force Regenerate Thumbnails plugin to regenerate your thumbnails. After doing this, all sizes you don’t want included will be removed.
