I think the argument is specific to images, which tend not to have as
significant of copyrightable changes made to them as software
libraries. Sure, maybe a newspaper cleans up an image, lowers the
resolution, and converts it to black and white before including the
image in the newspaper, but this is not a significant creative change,
so the benefit of having those changes released under a free license
For software libraries, weak copyleft serves a purpose. For text,
weak copyleft serves a purpose. For images, much less so.
