This summer I tried to write a hiking route,
illustrated with pix of the
plants en route. Most photos I could provide from my own walk along those
trails, but for some I tried to find some on commons. Inclusion of 1 or 2
photos from commons would force me to publish the entire 3 page description
under GFDL, instead of CC-BY-SA, <stress>and</stress> include a n-page
complete GFDL text. Very unpracticle.
If it's a web page, you could simply
place a link to it.
Note that GFDL has no provision for these practical
problems.
That's why commons suggests using a dual GFDL Cc-by-sa for the
images.
Also, not all photos of commons are GFDL. We probably have as many
Public Domain images as GFDL (and there're also many CC). You had bad
luck with the license of those 2 images you needed.
Moreover, you can always ask the author to (re)license it, either with a
generic CC license, or giving you permission to use it on the route. I
see no sensible reason he wouldn't accept to do it.
