Hello Samantha, this E-Mail is sent in reply to a comment on my Wikimedia Commons talk page [1] where you asked for permission to use the "Cumulus clouds in fair weather" image hosted on Wikimedia Commons. I'm sending a copy of this E-Mail to the general Wikimedia Commons discussion list so as to keep a record of this correspondence, and in case anyone else would like to chime in and offer you further advice.
Firstly, to answer your request, yes you may use that image as long as you attribute the author (Michael Jastremski) in some way and inform your users that the image came from Wikimedia Commons, e.g. by supplying a hyperlink to the image page. There's further information on using media from Wikimedia Commons on the commons wiki [3].
Secondly, you don't have to ask for permission to use media from Wikimedia Commons, it is a repository of freely licensed media which means you never have to ask for permission to use the media hosted therein. You merely have to fulfill the license requirements applicable to each piece of media you use. Usually this means stating the author of the image, its source, and informing the user what license the image is under.
