	# imgur redirecting direct image links from t.co on the first click ?
	# A subsequent visit in the same browser seems to work fine, so maybe
	# they remember it via the cookie.

	# 1. See i.imgur.com/foo.jpg link in a tweet.
	# 2. Visit it with a redirect through t.co.
	# 3. See imgur.com/foo page instead of just the image.
	# 4. Visit the same link from (1) again.
	# 5. See the regular image at i.imgur.com/foo.jpg, as usual.
