I love how doors and locks communicate such a powerful message – one of curiosity, control, and even mystery. Context is king, of course, but it’s easy to use doors for just about any kind of stock photo needs, whether an ad design for poster printing or the background for a web page.

This round-up of doors and locks are all free for commercial use. Make sure to take the time to thank the photographers for being so gracious with their work. This collection has a little of everything, from grungy to modern to ethereal. Take your pic(k) and enjoy!
