The thumbnail of an asset is the visual preview displayed throughout the platform, including in the library, search results, and shared views like Portals and Showcases. Customizing the thumbnail helps ensure the asset is easily identifiable and well-presented across contexts.
Note: Thumbnail updates are available for individual assets only and cannot be done in bulk.
Improvements to thumbnail customization are under consideration, including more precise cropping and the ability to upload custom thumbnail images. If you require more control over thumbnail appearance, please contact support to discuss options.
