Every year or so when I have a little discretionary income, I like to download images for use on my covers and in my blog and for personal projects that need to be jazzed up with graphics and illustrations and photos. I use various different places, but this month I'm taking advantage of a sale on Bigstock. One of the projects on my "to do" list is to put together a collection of fairy tales filtered through a steampunk aesthetic. I've never really written in steampunk but I enjoy it when I run across a well-done story in the genre.
Indie Author Services does that--but I really like playing around with images and font and typefaces and graphics. And I love having these images to play with.
