[SR-Docs] Permission for puplishing sip-router History on German Wikipedia

Hi There, last few days i've bee very confused about the si-router project and all the ser things arround it. So in a few hours I browsed the web and finally i wrote a wikipedia article in the german wikipedia. So... these guys are now very concerned about if I have the permission to publish this Picture. The picture I'm talking about can be found on the following URL: http://sip-router.org/wp-images/sip-router-history.jpg My Question is: Are there any restrictions regarding this picture? Am I allowed to pubish it on the german wikipedia? Quote from the Wikipedia: Um das nachvollziehen zu können, vermerke bitte die Erlaubnis auf der Dateibeschreibungsseite in der Zeile „Genehmigung“. Außerdem muss der Urheber/Rechteinhaber die Genehmigung zur Veröffentlichung per E-Mail an permissions-de(a)wikimedia.org bestätigen. Dazu verwendet er am besten die Standard-Textvorlage. Basically it's an appeal to the owner of the picture to write a mail to the adress permissions-de(a)wikimedia.org to grant the publishing. Thanks for ur help... myname
