Hi Celandine, Bonkers is right, thought a short version might help too.
1) On any page click on the "Your homepage" link under the questions tab.
2) Click on the 'Update profile' link next to the question mark photo on the left.
3) Update the 'Change your picture' field.
Done :o)

Thankyou very much Bonkersbon and Peter. I've managed the first part - transferring the picture. Now for the rest!!
