Patch Test only uses images that carry no copyright restrictions at all: CC0 dedications and public-domain works. Credit is not legally required for any of them, but we read our images the way we read an ingredient list, so each one gets a line below: page, maker, original file name, source, status. All were cropped and resized for the site, and you will not find product packaging or brand logos among them.
