Hallo Rene,
»» <td><a href="graphix.html" onmouseover="image.src='./images/graphix2.gif';" onMouseOut="image.src='./images/graphix1.gif';">
<img name="image" src="./images/graphix1.gif" border="0"></td>
»» <td><a href="logoz.html" onmouseover="image.src='./images/logoz2.gif';" onMouseOut="image.src='./images/logoz2.gif';">
<img name="image" src="./images/logoz1.gif" border="0"></a></td>
Dein Fehler liegt im Aufruf image.src="" und darin, daß alle deine Bilder den gleichen Namen haben.
ändere es wie folgt ab:
<td><a href="graphix.html" onmouseover="document.image1.src='./images/graphix2.gif';" onMouseOut="document.image1.src='./images/graphix1.gif';">
<img name="image1" src="./images/graphix1.gif" border="0"></td>
»» <td><a href="logoz.html" onmouseover="document.image2.src='./images/logoz2.gif';" onMouseOut="document.image2.src='./images/logoz2.gif';">
<img name="image2" src="./images/logoz1.gif" border="0"></a></td>
Viele Grüße
Antje
