validating again

somehow when i was wailing away at the wordpress template i added some code that was causing this page not to display in internet explorer (on the mac). nobody really complained about it, although tina brought it to my attention, and yesterday i finally cleaned up the errant tags and erroneous values.
the only problem now is that the image for the banner isn’t showing up, even though both the html and the css now validate. i imagine that IE will not load the image from the css, where i have it now. at some point i need to convert the header to a header.php, but that will prolly have to wait.
