Well, most distributions cache screenshots on their own and serve them
from their infrastructure (Debian, Fedora, Ubuntu and OpenSUSE do
that), while only a few use the upstream-provided URLs directly (I am
only aware of Arch right now).
Caching stuff allows distros to provide resized thumbnails for smaller
downloads and also allows blocking certain screenshots from showing up
in the software-center retroactively (e.g. in case someone added
non-free copyrighted material there, and we realize that only later).
This is just FYI, I still think a Git-Annex $whatever based repository
of screenshots is better than hotlinking them into Phabricator or
Quickgit.
