One of my new gaming buddies recently asked for advice about finding inspirational pictures for RPGs. He'd been mostly looking at video game concept art (which is a pretty good idea in itself).
Responses were pretty typical. Google searches. Deviantart. Whatever.
I suggested that he start from some pieces of art that he likes, find out the artist, and look at their online portfolios.
Then I saw someone suggested a particular Pinterest board... and it occurred to me: tons of people have RPG inspiration Pinterest boards. Why not let the cloud work for you?
