2. Copyright and utility of images in documentation (firstname.lastname@example.org)
These images were part of the ORIGINAL LibTiff distribution test image set and were distributed by Sam Loeffler. They can be used to test various capabilities of the library and the utilities. I don't know if anyone can be said to own them other than Sam.
With the conversion to Sphinx, I've copied over the use of all the images on the same documentation pages with the exception of the documentation icons. However, they don't appear to have any particularly obvious connection to the pages they are associated with or any obvious connection to the TIFF file format or library. If the origin and copyrights are unclear, and they don't add any particular value to the documentation, would anyone object to removing them all?
As a recent effort to read YCbCr JPEG encoded TIFFs shows, it would be good to keep them as test cases.
