Dag Tjerk

Het is niet "Febuary" maar "February"
Je zult in end4 en start5 2004 bedoelen waar 2003 staat.

de >= en de > schelen 1 miliseconde
javascript versie specificeren is niet zinvol
"<!-- Beginning of JavaScript -" ook niet erg zinvol

================================================

Ik heb de zaak nog eens wat leesbaarder opgesteld,
probeer het maar eens zo:

<SCRIPT>
var start = new Array()
var end = new Array()
var beeld = new Array()

var today=new Date()

start[0]=new Date("October 8, 2003")
end[0]=new Date("November 7, 2003")
start[1]=new Date("November 7, 2003")
end[1]=new Date("December 6, 2003")
start[2]=new Date("December 6, 2003")
end[2]=new Date("December 20, 2003")
start[3]=new Date("December 20, 2003")
end[3]=new Date("January 18, 2004")
start[4]=new Date("January 18, 2004")
end[4]=new Date("February 4, 2004")
start[5]=new Date("February 4, 2004")
end[5]=new Date("February 20, 2004")
// end[5] date changed for testing
start[6]=new Date("February 25, 2004")
end[6]=new Date("March 18, 2004")
start[7]=new Date("March 18, 2004")
end[7]=new Date("April 11, 2004")
start[8]=new Date("April 11, 2004")
end[8]=new Date("April 22, 2004")
start[9]=new Date("April 22, 2004")
end[9]=new Date("May 5, 2004")
start[10]=new Date("May 5, 2004")
end[10]=new Date("June 4, 2004")
start[11]=new Date("June 4, 2004")
end[11]=new Date("June 11, 2004")
beeld[0]='india.gif'
beeld[1]='thailand.gif'
beeld[2]='laos.gif'
beeld[3]='vietnam.gif'
beeld[4]='cambodja.gif'
beeld[5]='thailand.gif'
beeld[6]='mexico.gif'
beeld[7]='guatemala.gif'
beeld[8]='honduras.gif'
beeld[9]='nicaragua.gif'
beeld[10]='costarica.gif'
beeld[11]='usa.gif'
var b = 'nederland.gif'
for (i=0;i<=11;i++){
if ((today.getTime() > start[i].getTime()) &&
(today.getTime() < end[i].getTime()) ){
b = beeld[i]
i=100
}
}

var t="<IMG SRC='Images/waar/" + b + "' WIDTH='137' HEIGHT='103'>"
document.write(t)

I have the script below to change an image depending on the date upto

It will work if we ever have a month called Febuary. The present month
is called February.

Better to use new Date("2003/02/14") // less typing.
Your code is very repetitive. It could be shortened by using array
data, something like :-

var Data = [
{C:"potaniland", S:"2004/05/06", F:"2004/06/07"},
{C:"lumbago", S: ...
... ]

for (J=0; J<Data.length;J++) with (Data[J])
if (today>=S && today<F)
document.write("<IMG ... waar/", C, ".gif ...")

where today is now a string YYYY/MM/DD.

In fact, you only need to store the start date; scan until you find one
<= today, then finish (use break). Put a "catch all" of 9999/99/99 at
the end, preceded by one for Nederland.
