Create A Forum - Support Forums

I'm new to all this
i have a groiup on FB which already has 400+members and I feel we need to move on from FB
i am trying to work out things as i go
this is me
http://hinckleyyummymummies.createaforum.com/index.php
I have the 'light' style
i have worked out how to add boards, catorgories, calendar and albums so don't think i'm doing too bad but i'm stumped on adding a picture or logo at the top
the images i am after are either of attached
i think what i need is in
style manager, headers and footers,
but when i get there i just get confused
 
thanks for any help or advice

I'm interested to know this as well, want to know how to add a logo to forum
