Update certin page on Website

Hi,

I am designing a website for a friend who is a driving instructor and he wants to update two areas of the website himself as it will happen quite frequently: the gallery and a Successes page. Is there any easy way for me to set this up for him to do himself bearing in mind he is a little bit of a technophobe?

I am using Xara Web Designer 10.

Please let me know if there is any additional information you need but i am just looking for an idea to start with

Thanks
Gavin
