10 years ago Totally possible, but I don't know how to do that yet :grimacing:
We're changing the background now by setting the Mac OS default background to the selected image, then clearing out any desktops we've set manually.
In order to set a different image for every space, we actually need to understand how desktoppicture.db works (which looks a bit gnarly).
I may tinker with the db a bit and see if I can figure it out, but feel free to explore yourself and comment on your findings.
Here's some poking around:
> db = SQLite3::Database.new(osx.desktop_image_db_path)
> db.execute "SELECT name FROM sqlite_master WHERE type='table'"
[["pictures"], ["preferences"], ["spaces"], ["displays"], ["data"], ["prefs"]]
> db.execute "SELECT * FROM spaces"

Could be possible to implement a way to set different images to each monitor?
Something like:
