How to create a new row of boxes using divs?

[William Leigh]

Hi guys,

Hope someone can help.

I have a webpage that I need to adjust the layout on and it is in divs and I've not used them before.

The page as it currently looks is here: http://violetproductions.com/portfolio.html

I want it to look like this:


I am rather out of my depth here and a bit of guidance would be really useful. I need to be able to add more of the thumbs at the bottom when requested. I understand specifying an item in CSS i just don't know how to position them correctly and how to essentially create a layout for what I want!

Thanks for your help,

Will
