What would you guys think of a Daily Dose of Art? Artists always credited, naturally.

Also, when you submit/post (or possibly it appears when you edit a post) there is a field specifically for "source", that way you can have the artist info double sited, or if you found it in one place but their main body of work is another. Just FYI.

That’s harder to see

Can always do both. Post it in the source and the comments. It's the same link, you just press "paste" twice

Because that is reasonable. Obviously every piece of art shares on here is done with the expressed permission.

I’m an artist, I’ve had my art reposted without my permission too often to think it’s acceptable.

I honestly don't know how the logistics of that would work out... I'm about to start a new semester at university, and I have the time to find the art, and even find the artists, but contacting each and every one might pose a problem. :')

A lot of artists do say feel free to share their art somewhere on their pages.
You could realistically type up an email and then send the exact same email to any artist you want to show the work of. Maybe don't start until you've had time to collect a few plays, and then you can always show more than one piece by the same artist, especially early on.
That being said most artist who put their work on the internet without putting it behind a paywall actually want it getting spread around as long as they are getting credit. So if you can't get okay from artist, I thinks urs probably fine as long as they haven't clearly asked not to have their work shared around.
