Need help with a simple java script

[angeliq]

I'm a total n00b with java scripts but I need one for mt personal site.Namely,it's a script that changes an image 4 times a year,this is the script I need help with:


<script language="JavaScript">

var pics=new Array();
pics[0]="images/ winter.gif";
pics[1]="images/ spring.gif";
pics[2]="images/ summer.gif";
pics[3]="images/ fall.gif";

var UW_Date=new Date();
var d=UW_Date.getDate();
var m=UW_Date.getMonth()+1;
var s;

if(m>1&&m<=3)s=0;
else if(m==3&&d>19)s=1;
else if(m>3&&m<=6)s=1;
else if(m==6&&d>20)s=2;
else if(m>6&&m<=9)s=2;
else if(m==9&&d>21)s=3;
else if(m>9&&m<=12)s=3;
else if(m==12&&d>20)s=0;

document.write('<img src="' + pics[s] + '">');

</script>

*BOLD - I know that these are the dates that define when the image changes but I don't really get what is what here.If anyone could help me with,if I for example needed the scripts to change the images on the following dates:

September 5th
October 6th
November 8th
Decemberr 9th

Thanks in advance :o

Thanks! You saved my butt. Thought I could repay. I modified your script (very little), tested it, and found this works.

I defined the four seasons like this:

Spring= 3/20 - 5/15
Summer= 5/16 - 9/4
Autumn= 9/5 - 11/23
Winter= 11/24 - 3/19

You'll likely want to change the names and directory locations of the seasonal pictures.

I've been wanting to have more 'relevant' graphics on my site that rotate. I've been attempting without success. Thanks to you - I now have it.
