No one will nor can hinder you to take any of the images on this site.
Nevertheless images and artwork of this site are original. In that context it would be a respectable move of yours to quote author and origin next to the image you’re using from here to indicate, where it came from.
If you’re trying to make money out of his art without notice,
Ropinsky reserves the right to get extremely & extensively dinner-invited by you (you pay), or slice you with a monomolecular cyber-fiber.
Thank you.
