M-A-Styles

Please forgive my lack of understanding of the many aspects of phpBB, themes, styles, etc. A lot of it makes sense to me, and a lot doesn't!

I'd like to add the Gallery feature to my BB. I see it contains updates to the ProSilver and SubSilver styles, but I use ProFormell, of course. What do I do to install the Gallery when I use the ProFormell style?

Just run the prosilver instructions on proFormell.
