First of all, neither you nor your program's users will have any
problems derived from what you described. Wikimedia's content is all
freely redistributable, and is always tagged with the licensing
information.
Some licenses accepted by Wikimedia are not compliant with Debian's
Free Software Guidelines. For example, today's photo is licensed under
a very weird license, CE Photo:
https://commons.wikimedia.org/wiki/File:Lahad-Datu_Sabah_Mount-Silam-Red-Crab-Geosesarma-aurantium-02.jpg
However, downloading and displaying it with the correct attribution as
you mention is _always_ legally possible, as that is one of
Wikimedia's core values. You can read more on Wikimedia Commons'
licensing rules at:
