Unguessable tokens have a long history of use in our field (CSRF tokens,
etc) and having one lock access to an image is relatively legitimate.  If

I think the difference is how long you expect that token to be kept. The
link given, afaict, is a permanent one, unlike csrf tokens or various change
password tokens.
