How To: Manage Thumbnails

Thumbnails are smaller versions of images that you upload to the site. Thumbnails are used wherever a full-size image isn’t necessary. Thanks to the smaller size of thumbnails, pages load faster.

By default, product thumbnails are generated automatically from the images you upload. You can change the size of thumbnails on the Settings → Thumbnails page.

Once you change the settings, delete the old thumbnails; new ones will be generated automatically. To delete thumbnails, go to Administration → Storage and choose Clean up generated thumbnails.
