Can't have contributions when the images likely aren't even under a license that would allow use like this. I guess it's better not to say where they are from and hope people don't notice...
The image of the girl lying on the floor is a screencap from the "Whisper of the Heart" movie. I doubt it's licensed. Various "lo-fi" YouTube channels used to do that as well, but got copyright strikes and changed to original artwork.
> Dimitri chose the character of Shizuku Tsukishima from the Studio Ghibli film Whisper of the Heart as the face of the channel, with footage of her studying or writing used in the streams. When the popularity of the streams ultimately led to some getting taken down for copyright violations, Dimitri decided to maintain the Ghibli-esque aesthetic but with an original character and put out a call for artists.
Yes, although I’d note that among people who listen to lofi music, the “anime girl studying with rain outside the window” animation is an extremely well known meme.
The streams are just the name as a youtube video. For example if you click the "lofi hip hop radio - beats to relax/study to" in the bottom left (r what ever you are on) you'll see all the streams. Copying that name and pasting it in Youtube will show you the stream.
Though I do agree a link to them (since there is no mention of Lofi Girl anywhere for example) would be nice.
The project has a better chance of survival if it follows the rules of the platform sourcing their content. I think that warning somebody that they're standing on a cliff edge is the polite thing to do, even if the cliff is man-made.
