Got more cliparts to hide due to licence incompatibility. These are under <a href="http://creativecommons.org/licenses/by-nc-sa/3.0/">CC-NC-BY-SA 3.0</a> <a class="moz-txt-link-freetext" href="http://www.openclipart.org/index.php?pretty=detail/67159">http://www.openclipart.org/index.php?pretty=detail/67159</a> <a class="moz-txt-link-freetext" href="http://www.openclipart.org/index.php?pretty=detail/67153">http://www.openclipart.org/index.php?pretty=detail/67153</a> <a class="moz-txt-link-freetext" href="http://www.openclipart.org/index.php?pretty=detail/67147">http://www.openclipart.org/index.php?pretty=detail/67147</a> I have one question. Is CC0 compatible with Public Domain? I mean, can they licence it under CC0, then upload to OCAL, which then "Our version" becomes PB and the rest is covered by CC0 , or does it have to be only PD? The problem is that : PD isn't valid in many places outside of the USA.
