OK, I have a page (code below) that I would like to have work by having the images displayed in rows. However, there may be not be enough images to complete the row - go all the way across the displayed area. I would like (1) all the rows to be more centered horizontally in the display and (2) all the "excess" images (not able to fill the row) be centered horizontally.

Tried some things I found on the web, but nothing seems to work.

Please tell me where I went wrong.

Oh, this is not live yet - still on development machine
