Because to can be a part of Kodi it's under CC BY-NC-SA 3.0 licence like all other addons and projects here or also the stuff you can see on fanart.tv or so.
It's just a comment under every image to make this preventiv clear to avoid complaints from copyright nerdists.

Then there are difficulties with the posters.
I liked the idea of the archive. For example:
Beauty and the Beast (2017) original - A.rar;
Beauty and the Beast (2017) retouched - B.rar;
Beauty and the Beast (2017) keyart - C.rar.
It turns out from this, with impunity, I can open the download only on B.rar (what I did myself). Then does the meaning in the database on deviantart disappear or am I not understanding something?
I also found information about file sizes - 30MB per file and 200MB to archive, but I didn’t find information about the total size of the storage, which is important, since the database size can be very large.
