Link to galleries, or make multiple copies?

[uterpie]

When making free sites using an existing gallery, should I:

A) link to the original gallery from multiple free sites
(www.domain.com/free_site --> www.domain.com/gallery)

B) make multiple copies of the original gallery, one for each free site
(www.domain.com/free_site --> www.domain.com/free_site/gallery)

I hope thats clear enough. I have been doing A, and I heard that I SHOULD be doing B. But B requires more disk space and more time uploading, so I'd rather stick with A unless it means I'll get rejected.

Thanks for any help,
