Provide a Thumbnailing API

It would be great if the native REST API and WebDAV API could offer a feature to retrieve thumbnails for hosted photo files.

This functionality could be similar to OneDrive’s Thumbnail API, Dropbox’s get_thumbnail, or Nextcloud’s “preview.png” endpoint.

In the best case I can specify the dimensions of the thumbnail (like OneDrive offers).

The use case is to enable seamless integration of my photo organizer app with a Seafile host. Currently, downloading all original image files to generate thumbnails locally is quite slow, and having an efficient thumbnail retrieval option would significantly improve performance.

Hello, there is an url which you can get the content of thumbnail, the url is like:
/thumbnail/<repo_id>//<file_path>
You can also refer to the debug network console in the browser and check the url for requesting a thumbnail.
