I love looking at fantasy art. The three places I go the most often are DeviantArt, Elfwood, and Epilogue. Now, Elfwood and DeviantArt have a lot of amateur pieces so you have to pick your way through the galleries. Epilogue is a lot pickier about what they accept so it's easier to find good fantasy and science fiction art there.
But those pictures are not the only places I've drawn my inspiration. Pictures of ancient Roman ruins have inspired buildings in my stories. Photos of recreated ancient houses and ships have given me ideas on how to make the same things in my world more realistic. Pictures of fashion through the ages gives me an idea of how to pattern the clothing of the characters of my stories.
So go find a picture that inspires you and write your 1000 words.
