cb,
bad, bad host. For validation, why not write them and ask them to at least complete their "<script>" tag and add an alt to the image.
Hey divaone. Thanks for the feedback. I have emailed them on many occasions. Apparantly, they aren't too knowledgeable on customer service, or XHTML validation. Either way, they've never done anything about it.
Honest thoughts: I love the colors! Not a big fan of the green diamonds at the bottom. Probably would've done either micro or bold stripes instead, then moved the text below all design and centered. Just MHO. On each page the thumbs don't line up with the instruction/big image box. A valign issue maybe? But I appreciate them being shown on the same page. Contact us page's center col is way down the page. There's no color bg for the "dishware" heading (or maybe would not show). The "paintings" header should be padded left a bit like the other headings. And lastly, IMHO, the alt tags are too detailed. This is one opinion of Jakob Neilsen that I do fully agree with: Link. I understand the reasons for it, but maybe separate pages for the images for accessibility? Overall I like the forethought you put into the design and development!
I did try stripes and I found that it brought more focus to that section of the page than the page itself. Therefore, I chose the subtle coloured tile just to accent it.
Thumbs don't align? I tested this on IE 6, Mozilla, Firefox and Opera on the PC and it seems to align for me. Same with the Contact Us page. What browser and platform are you seeing this on?
Dishware bg image is #fc0. The container background is #fc6. Kind of subtle, I suppose.
The 'Painting' heading is an <h2> element. My style sheet dictates 'padding-left: 10px;' for all <h2>'s, so it should be the same.
About Jakob Neilsen. I guess the real challenge of making an art site accessible is trying to describe to the person accessing your content what they are, well, accessing. The challenge I had is giving the user an idea of the artwork on the site. I don't know how it's possible to describe artwork in a couple of sentences. I think that's impossible to do. However, creating the 'alt' and 'title' values is first for the compliance of accessibility and then to try to describe the artwork. I can see Jakob's point about overdescribing something, but I think in this case of trying to make the site accessible and the nature of the site, I tried my best.
Seperate pages for accessibility? I think then I am defeating the purpose of trying to design with accessibility in mind. I believe the two can go hand in hand if the effort and time are put in your site. IMHO

And....thanks for the compliment on the design and development. I try my best
cb.
