My advice would be to create a page User:Cyanide/test, put the template at User:Cyanide/gallery and add the CSS to the site CSS. The gallery code that the Wikia server outputs can take any input at above 120px (example) and shrink it to its need. Just make sure that faces are centered like this one (originally at 200px).

If you need to change the number of columns, it is indeed the width that you'd change. Otherwise, its fine :D
