Sorry the Unconfirmed user think is a bit of an awkward anti-spam measure, but basically you need to do one more edit of a wiki page. Any wiki page. And then you'll be able to do uploads.
I see you've done 9 edits so far: Special:Contributions/Laurad ...and the threshold is 10.
For example you might create this page: User:Laurad e.g. just write "Hello I'm Laura" (it's your user profile, so write whatever you like!)
After that you'll be a confirmed user!
Hey, Harry Wood! Many thanks for the quick and very helpful reply. I have made the page so I'm guessing all should be as expected now.
