CSS/XHTML coding of picture rows

Hello, I'd love to get the following attached image coded in valid CSS/XHTML. That image gallery snapshot comes from this link: [login to view URL] (so please refer to it so you can understand how to code it). The code should be valid in all major browsers, and should use lists (ul/li) in the XHTML to display the gallery (and styled accordingly just like you see in the attached image). I'd like to see your CSS/XHTML coding quality, so please submit your previous work if you can. If you have any questions, please let me know. Thank you!
