Just wanted to share this awesome stock photo website with you.
Stumbled across this site called tookapic.com where you can download free stock photos. Currently, according to the site, there's over 3500 totally free stock photos that are filed under the CC0 (Creative commons zero) license. That means (citing from site): "your photos will be licensed under Creative Commons Zero license. This means users can copy, modify, distribute and use the photos, even for commercial purposes, all without asking permission."
It's completely free and once you sign up - go and browse! Remember to activate the filter "Free photos only".
