Excellent HTML! The only error was including the first two lines of HTML below before the BODY tag, when they should have been placed after (as now - I have corrected it here).
The only other point concerns the picture. It is best to reduce the size of the picture file, rather than let the browser download a large file and then forcing it to resize it. This is particularly important when working with a browser at home and, for example, a 56k modem. (It is a very nice picture.)
