I don't get why Google hasn't cleaned up the Pinterest spam in Google Images:

- Using Google Images search for: fun crafts.

- Results loaded with Pinterest hosted images.

- Visit any of those Pinterest hosted image pages

- The page on Pinterest may not include the image you are looking for (anymore)

- Or the Pinterest page may be an intermediary page that links to some other external website with the original image (Google doesn't give the original website the traffic)

- After 5 seconds you start getting prompts to create a Pinterest account
