Where do you get your photos for covers?

Shutterstock! I like Canva if I'm looking for something a bit more "subtle."

I like Fotolia too, but most times I commission a photographer: Varian Krylov from Strangeland photography, She does fantastic M/M photography at excellent rates for full usage rights (comes in handy for banner stands and merchandise at conferences etc).

I really like the new AdobeStock! I've had good luck there.

One girl drew one of them for Sleeper and the rest I got from Wikiphotos. (I'm too poor right. )
