the text in alt tag below does not show up on the website when you bring your mouse over the tshirt pictures. How can I fix it? The website is www.robotbuy.com
By the way, as an extra info, when I removed the document type declaration and just wrote html on the very top, it worked (but of course I need a document type declaration). I didn't have a particular reason to use that doc type anyway, but saw it as commonly used so just copied it. If I need to use another document type declaration what should it be? If not, how can I fix this problem?
