Let's make a strong copyleft license that appeals to photographers.
In my opinion, that is only possible if the copyleft provisions unambiguously transfer to text written to accompany the image. Anything less, is little better than CC-BY. Most people that use photographs do so for the purposes of illustration rather than for the purposes of making derivative images. Hence copyleft provisions that apply only derivative images, and not to the text being illustrated, are intrinsically weak and of little impact.
I could not have said this better myself. Exactly. Because of the way still illustrations are typically used and reused, a copyleft license which does not extent to all derivatives in fairly broad sense (i.e. a derivative is a work which contains the covered work) might as well not be copyleft at all.
And since the cc-by attribution clause is soft (allowing service providers to take attribution), I'd argue that if you're going to do cc-by you might as well do 'PD'. Basic kindness and respect still demands attribution for PD works, and since most people can't afford to go to court every day it is basic kindness and respect that is getting them attribution under cc-by in most cases anyways.
