better yet..why not just pay a few bucks for a legitimately licensed image?
I don't understand why anyone would risk being sued when you can just get away with paying $50 to some broke college chick to license out an image.
1. stock commercial photos have shittier CTR in my experience. CTR is much better when it looks amateur.
2. because you need to split test a shit load of images/people to optimize your ads.
