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

thanks i've found that bit, but my pic is on my computer,
is there a way to get it a url, or where do i find it if it already has one somewhere?

thank you soo much, I remember getting a URL for something once before ages ago,
but couldn't remember for the life of me how I had done it, was photobucket
now both kids are finally settled in bed (one very uncooperative 4month old tonight) am off to see if i can sort it

thank you soo much
success, although a little oversized, but now I have managed to get something on I can work on size etc myself
