I always enjoy photo story prompts, so we've put another one up at Dark Valentine. We're looking for flash (under 1000 words) inspired by the photo. Here's all the info.
We don't pay for the stories published on the site but Dark Valentine is a paying market for stories published in the magazine. Our first issue will be available in mere weeks, but we're open for submissions to issue #2 now. Here's a link to our guidelines. Dark Valentine is looking for any sort of dark fiction--you pick the genre.
