I occasionally use stock photos in this blog and in a few other ventures, like graphic design sidework. If you're like me (i.e., have a budget of approximately $0) and are also looking for gorgeous stock photography, this list should help. These three services are my favorites and the only ones I use -- and they're each FREE!
Death to Stock is a project by Allison Lehman. Sign up for monthly themed photo packs delivered to your inbox. I turn to Death to Stock for on-point lifestyle photos, and good pictures of people. The only downside I can see is the full library isn't available unless you kick in for the premium package. (The top image in this post is from Death to Stock, too.)
Seven photos emailed every seven days, and the searchable library is available to all! Great nature photos.

10 new photos every 10 days, and I can always find a really, really beautiful gem in the searchable library (which you can also search by category).
