Stock image illustration (licensing)

[Bagas Sanjaya]

Hi,

Imagine that there is a new Linux kernel contributor, contributing
documentation patches. As it is the habit from her company, she adds
stock images from various sources (which may or may not be related
to the doc), e.g. freepik or pexels [1], as illustration.

However, on the source file, the image requires attribution. Yet,
the attribution instruction doesn't mention image license (she
attributes as "Illustration of foo by bar on pexels"), hence
all rights reserved. Can that stock image be added to the kernel
docs (which is licensed under GPL)?

PS: none is lawyer here.

Thanks.
