[Plugin: NextGEN Gallery] Centering Thumbnails… Had It / Lost It

Hi,

I had my thumbnails centered until the recent update and… my fault, I can’t seem to remember how I did it previously. I have read through the help topics when I centered them last time but having no luck now.

Is there an easy solution to centering thumbnails in a post?

Thanks very much.

John
