I have a plan to use on my page content mix under different license sources: text materials from Wikipedia under CC BY-SA 3.0, and some images from Flickr under CC BY 2.0 and most part of images from pixabay under original license, which is based on Creative Commons' public domain deed CC0. All links to source pages will be given. Can I finally publish all content under CC BY-SA 3.0 without additional actions or maybe I should use different type of license like CC BY-SA 4.0?
Is I correctly understand CC licenses inner compatibility?
