We updated IMDb script.
Ratings, thumbnails and some other info was missing there.
We should start noticing more thumbnails on subtitles now.
If it shows as "No Thumbnail Yet", hitting "
IMDb Update" should resolve that.
If it says: "
TV root Series OK queued for update later," that particular episode sub page should get a thumbnail, the rest of the TV series episodes will get updated automatically in due course. You don't need to do all of them individually.
Process should work for movie subtitle pages, too.
If it's a brand new released series that didn't have any uploads before, it may take several days to retrieve the thumbnail.
