I guess the only reason why the bug report is only about this image is
that nobody detected the other images.

Would you consider a free license for these images?

I will not question your arguments about the sense of those images.
There is simply the fact that we are not allowed to ship non-free images
in Debian main.  There might be an option to maintain an additional
package cimg-data or cimg-examples in Debian non-free.  Could you
specify all images which are not free (and can not be released under a
free license).

I will not judge about this since the file in question can not be
distributed because of the license which is a harder fact than sexism.

You are free to keep it inside cimg - but I need to remove it from the
Debian package if cimg itself should stay in Debian main.   That's no
matter of personal opinion but this are the rules Debian is build upon:
We only deliver free code and data.

Kind regards and thanks for your quick reply
