Adding a custom thumbnail
- Navigate to an asset's detail page .
- Use the action menu and choose Add custom thumbnail.
- Choose a supported file type from your local storage; this file will replace the system-generated thumbnail.

Document pages and custom thumbnails
You can use a document asset's pages to choose a custom thumbnail. Supported document file types include DOC, DOCX, PDF, PPT, PPTX, and INDD files.

Removing a custom thumbnail
Custom thumbnails can be removed by resyncing an asset with a custom thumbnail. When an asset with a custom thumbnail is resynced, a new default thumbnail will be generated; in some cases with some file types, this may appear as a generic file type thumbnail. This action will delete the custom thumbnail and it cannot be retrieved.
- An asset's thumbnail is used when performing a visual search . This means if an asset is using a custom thumbnail, visual search results will be based on that thumbnail rather than the original asset.
- If an image asset is manually repurposed , the preview used during the repurposing process will use the custom thumbnail. The final repurposed result will reflect the underlying asset rather than its thumbnail.
- If you are uploading an InDesign document and would like to preserve any template image content in thumbnails and previews in NetX, see our guide on INDD thumbnail support .
- Any reviews that include an asset with a custom thumbnail will use the custom thumbnail as the preview while viewing and annotating the review..
