By default, Asset Bank generates thumbnail files for assets upon upload. These thumbnails are the preview images used in areas such as the browse & search results screens, lightboxes & homepage saved/featured/recommended searches.

There may be times when you need to manually generate new thumbnails, for example after an upgrade to account for larger preview sizes, or when removing an old thumbnail and needing to regenerate a new one from the original file.

Admin users can action this within the Admin > System > Thumbnails Regeneration area.

A thumbnail regeneration can be run against:

• All assets.
• Featured assets.
• A singular asset.
• A range of asset IDs.
• The results of a previous search.

The thumbnail regeneration will run in the background so users can navigate away from this page once the process is running. Users browsing the site should not be impacted by the process.
