Ciao,
mi stò impiccando a sitemare un tema di un portale...non dovrebbe essere nulla di troppo complesso per chi capisce qualcosina di html.

Se andate su questo sito: www.pubmedeurope.com potete notere che c'è un'imperferzione grafica nell'inserimento delle 2immagini superiori:
si vede il colore di sfondo della tabella sopra e sotto le due immagini...non riesco ad uscirne....non capisco cosa ci sia di errato...il codice html è questo...credo sia qualche casino con delle tabelle...per favore sapete dirmi dove sbaglio?

codice:
<html>

<head>
<title>Welcome to my site</title>
