sue, I know there has been a few threads about this in the past but the best way to do it is, make a directory for your freesite, something like
domain.com/site-name. after you are done building your site you can do it couple of different ways but I do mine as follows
domain.com/site-name/mirror-one
domain.com/site-name/mirror-two
domain.com/site-name/mirror-three
and so on.... now copy your html files and put them in those directories and pull the images from the original directory which would be domain.com/site-name and you are all set. Every link list get an index.html
You can leave the original index which is in domain.com/site-name clean for use on your own hubs. I suck in explaining things but if you need help with it you can drop me a pm and I will show you some samples
