Thumbnails have a single entity field called Image Source entity. With the Image Source entity, you can quickly access the source of a thumbnail image. For example:
- If you manually uploaded an image for Shot_001, then the Image Source entity for Shot_001 would be Shot_001.
- If you enabled smart thumbnails, and the thumbnail from Shot_001 is derived from Version v001, then the Image Source entity for Shot_001 would be v001.
- If you have an Anm (animation) Task that receives its thumbnail from a linked entity, Shot_002, then the Image Source entity for Anm would be Shot_002.
- If you have a Note 1 that receives its thumbnail from an annotated frame on a Version, then the Image Source entity for Note 1 would be annot_version_6005.0.png (this is the attachment entity).
The Image Source entity field is system-owned and cannot be deleted.
Note: The Image Source entity can be retrieved via the API, though it cannot be set via the API. Additionally, the Image Source entity field does not support sorting, grouping, queries, or summaries.
