Ember downloads all actor images after the "Edit Movie" dialog.

Thanks, good to know. But... is there a reason it does that?
I don't save actor images locally and XBMC gets the images online when it needs to, anyway. So this is actually doubling the time (or way more, if I just update and already have poster/fanart) to edit a movie, only to get something I don't need and the program doesn't even keep.
The way I understand it, EMM currently loads the actor images (which takes up much time and bandwidth - for latter I don't care, but tmdb etc. might), then forgets about them instantly. So the images are downloaded just for the sake of downloading them. ^^

Couldn't this be optional, so that it is (only) used, when I actually want to save actor images in the movies folder? I think this would be highly convenient for users and the providers of all that stuff.

There is an option in settings to disable actor thumbs downloading: Settings -> Movies -> Files and Sources -> File Naming -> Actor Thumbs

That's what I meant with 'I don't save actor images locally'... I use the Frodo/Helix file naming with only Fanart, NFO and Poster checked, so actor thumbs shouldn't be anywhere on my drive, whilst they are still being downloaded (and then probably discarded) every time I update a movie.

It's kind of the same with TV Shows and Images in general. I can't update the whole shows info (meaning text only) without it redownloading every single image I already have.
Ex.: I added Season 5 of Boardwalk Empire. While episode-updates were done automatically, the show still showed as 'continuing'. So I do 'refresh data' (Ctrl+R), the text is updated, but all images are redownloaded aswell. It basically does the same as '(re)scrape data' (Ctrl+I), except that I don't get to choose, which Images I want.
