Hi,
Little blue boxes sounds like the pics aren't loading to the browser. Could be either a link or picture problem. If you are using eBay Preview to see the problem, are you copy and pasting the code to eBay's one-page lister?
Could you post the template at www.practicewriter.com and the link back to this thread?
A good online tuturial is at W3 Schools
