I too have been pulling the gallery css apart via FF & Firebug – I’ve centered many an item via <margin: * auto * auto;> but no matter how I tweak the cascade those little thumbnails won’t center. I wouldn’t think I’d have to hack the nggfunctions.php file just to center some thumbs.
where the where it’s getting that “float left” from, but so far I can ‘t see it – Firebug sure as heck can’t see it.
Shouldn’t really be that hard
