I'm clearly not an expert at this. I know the basics, and usually enough to get what I want done.
When I test the code I (I just use notepad to test) I get one long section of cubes, all straight down instead of two columns of four, some have the little broken image symbol, some show the link and work when clicked. No image appears for anything. There are no images for anything to mouseover.
It differs from what I wanted completely, there are no images. I haven't used the W3C HTML validator, I don't even know what it is. I'm running whatever the most current Firefox is.
