http://lifebylinda.uuuq.com/Santarem/images/slide/1.jpg doesn't exist, but
http://lifebylinda.uuuq.com/Santarem/Images/Slide/1.jpg DOES.
Capital letters make a difference on linux servers. Edit the javascript to look for /Images/Slide/#.jpg (for all 7 images) and just replace # with the right number.
your script will look like this:
CODE
<script LANGUAGE="Javascript">
function banner() { }; b = new banner(); n = 0
b[n++]= "<IMG name=randimg SRC='Images/Slide/1.jpg' border='0' ALT=''>"
b[n++]= "<IMG name=randimg SRC='Images/Slide/2.jpg' border='0' ALT=''>"
b[n++]= "<IMG name=randimg SRC='Images/Slide/3.jpg' border='0' ALT=''>"
b[n++]= "<IMG name=randimg SRC='Images/Slide/4.jpg' border='0' ALT=''>"
b[n++]= "<IMG name=randimg SRC='Images/Slide/5.jpg' border='0' ALT=''>"
b[n++]= "<IMG name=randimg SRC='Images/Slide/6.jpg' border='0' ALT=''>"
b[n++]= "<IMG name=randimg SRC='Images/Slide/7.jpg' border='0' ALT=''>"
i=Math.floor(Math.random() * n);
document.write( b[i] )
</SCRIPT>
