Art Files?

So I love the Sentinels of the Multiverse art and I was really wondering if there is any place where the card art is hosted online or a file dump of the card art? Love to make some cards my wallpaper or put them together for a wallpaper.

Here is a place to start. Also, check the other tabs there.

Also, Ctrl+Print Screen in the Steam version (each hero has an info page with all their card art) ;).
