  See D18006#387372 <https://phabricator.kde.org/D18006#387372>. In short, images were blurry when scaled and cropped.

  Aside from Plasma doing non-artist style cropping, they seem fine to me tbh.

  In your estimate, how bad would the added load be?

  +1 but we need to do some sort of a trade off here. IMO I'd keep all of sizes for "Next", but for T9817 <https://phabricator.kde.org/T9817> and T10220 <https://phabricator.kde.org/T10220> we're put in a pretty bad situation if having to ship all sizes because we'll be want to shipping large resolution wallpapers and quite a few of them.
  
  For instance, just shipping a certain old Plasma wallpaper adds 20 MiB to the plasma-wallpapers package, which is already almost half of its current size  (a bit over 40 MiB).
  
  For comparison's sake Deepin, GNOME and Elementary also just offer one size in this extra package from I can tell.
  
  Also might be worth mentioning that the new photographic wallpapers in T10220 <https://phabricator.kde.org/T10220> are CC0 or similar licence (Unsplash) and picked from third-party sites so there's no author involvement with KDE. We're also trying to select them based on whether or not it will get messed up with cropped.
