I believe in copyright. Using someones photos or images, even for good purposes or without monetary gain, is stealing. Just because something is “on the internet” does not make it free to use. Just because “everyone else is doing it” does not make it right.
All photos or images are either used under a Creative Commons license, copyright has expired, I have permission, or I have created the works myself. The skull and crossbones logo I am using was donated to Wikimedia Commons by Pearson Scott Foresman.
If you are an owner of a photo or image, and I have used your creation in error or have not correctly attributed your works in accordance with the license, please contact me and I will promptly rectify the error.
