Hi, can has a website using toghether wordpress and osm (that has odbl licence) a cc by-sa licence for his text and images?
I fear that your question is to general to give a correct answer.
As fara s I know, Wordpres is a framework to publish content on websites. So why does wordpress play a role here?
And: the raw OSM data is released by using the ODbL … if you publish graphics based on that data, you can choose different free licences, one can be CC-by-SA, I think.
The images produced using OSM data are “Produced Work”. See section 4.3 of ODbL http://opendatacommons.org/licenses/odbl/1.0/
