Rights & Usage
These are to the best of my knowledge available in the public domain based on the institutions participation in the Flickr Commons and the rules of Flickr Commons.
All photos are at the very least available for personal and non-commercial use (Medium articles, blog posts, personal projects, hero image for your 404 page). If you are curious of whether or not you can use it, check the institution’s rights statement through the link I provide to the original Flickr posting. Most prefer that you link back to the original flickr photo and mention the institution by name.
The pro photo packs are a service I provide —editing and curation — to make for your ease of use. I am not selling the photos, I am providing a service for convenience. Photos in the pro photo packs are collected from institutions that allow commercial use determined by the information provided on the institutions rights statement page.
If you believe a photo is in fact copyrighted or recognize that it violates use terms, please contact me and I will remove it immediately.
