Hello all, am new to this site, I must say the pictures I have seen are very outstanding, I do have one request

I found this picture on your website which I would love to use as my website's background

http://www.caedes.net/Zephir.cgi?lib=Caedes::Infopage&image=rosette_kpno_big_blue.jpg

I wanted to know how do I go about contacting the Author, who happens to be NASA, am not sure who to email or even if I need permission to use a NASA picture

I just wanted to make sure if I need permission from them before I used it as my website's background

I searched your site's FAQ but didn't see anything specifically concerning NASA pictures

Thank you in advanced for your help
