I haven't used MSN for years. I currently use Earthlink. But usually you get 10-20MB of storage for you.

I believe that you can use FrontPage or FrontPage Express to post your website.

I would contact their customer support, and ask them on how to publish to your personal space.

It would look something like somedotcom.com/yourname

or something like that.

If you had Earthlink I could tell you for sure, but you shouldn't have to pay any extra to publish some photos.

Hope this helps
