False dichotomy; when it comes to flights, they could show general information with links to flight companies. When it comes to images, they could limit themselves to small image previews / thumbnails.
Of course, one reason why I for one prefer to stay on Google Images (and have an addon to go directly to an image file instead of the site it's on) is that the sites themselves have so much cruft on them. And they kinda have to, because there's no money to be made on a minimalist image hosting site, while there's plenty of expenses - wouldn't be surprised if the brunt of expenses is abuse prevention.
