By default, Asset Bank generates thumbnail images for assets upon upload which are used as previews of the full file when browsing and searching in-app.

On occasion you may need to manually generate new thumbnails, for example after an upgrade to account for larger preview sizes, where the original source file is replaced/updated or if the length of a video preview is amended etc.

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.
