Center the whole gallery without sidebar

Now that I've gotton rid of the sidebar, I'd like to know what I change to have the entire gallery centered.

I know the code to center item is in templates/layout:
#gsImageView { text-align: center;}
gsImageView table { margin: auto;} which helps alot.

I tried changing layouts/matrix/templates/local/albumBody.tpl & singleBody.tpl and templates/local/global.tpl but that just left a big empty space on the left side or did nothing.

Can anyone tell me how to center the whole gallery?
