i need help with this too,   this is an awsome plugin , it has saved me valuble time.

but i also need to center the thumbnails. Ihave tried putting the code in a centered table, and centering the code in the table but it didnt work.  please advise.

Me too.

Horizontal centering with CSS is such a pain.

I did get this to work with everything in a centered table, but it's just a workaround.
