I've been using pixabay from time to time which you have suggested before. I think it definitely is better than sifting through google images as google images has a clutter of junk most of the time and the likely hood of you finding a nice stock photo is harder than using something like unsplash.

Also you have the added benefit (and the most important thing) of having copyright free images. Despite the talk about steemit is decentralised and you can do anything you want is not the right mentality.

Thanks for suggesting another site @stellabelle
