[cc-licenses] Clarification needed - Copyleft AND Share-Alike with Images

Hi Erik,

At commons.wikimedia.org several forms of derivates are in frequent use:
* removing watermarks
* combined pictures where individual images are PD, CC-BY-SA or GFDL

Perhaps I misunderstand your proposal, but your proposed change seems to
limit possibilities of the license under which many people published their
images at both flickr and commons. That does not seem reasonable to me.

Also, please keep in mind that the derivatives at commons.wikimedia.org are
not just combinations. These are a minority among the derivatives. Other
frequent derivatives are the partly colouring of maps to highlight a town or
provence, and the removal of watermarks.

kind greetings,
teun
