- * gimp_register_thumbnail_loader:
- * @load_proc: The name of the procedure the thumbnail loader with.
- * @thumb_proc: The name of the thumbnail load procedure.
- *
- * Associates a thumbnail loader with a file load procedure.
- *
- * Some file formats allow for embedded thumbnails, other file formats
- * contain a scalable image or provide the image data in different
- * resolutions. A file plug-in for such a format may register a special
- * procedure that allows GIMP to load a thumbnail preview of the image.
- * This procedure is then associated with the standard load procedure
- * using this function.
- *
- * Returns: TRUE on success.
- *
- * Since: 2.2
