Be a little more friendly for the generation of the text version: for

"blank" navigation icons, use ALT="" instead of ALT="blank"; also add
ALIGN=CENTER for the table, to get a slightly better affect in the
text (the table is full-width, so this doesn't change the appearance
when browsing the HTML).
