If the software being used is Gallery V1 then it can be upgraded to V2.
AFAIK, V1 is not being actively developed any more
I used Gallery 2 when constructing the Aldershot & Farnham Camera Club
site. I was able to customize the software quite easily to give me the
finish we required.
I you want to see what it looks like then visit.

As an aside, this is served from an eeeBox B204 running Fedora 11 that
sits on the shelf in my office.
