Hi i made a script that rotates a picture each monday on my websie but I only knew how to make it so it changes the picture for every monday in JULY. I would like the program to change the picture each monday for the whole year not just one month. I was thinking to make labels for each month in the script but I don't know how to use the LABEL command properly, how can i use the LABEL command? Does LABEL work like it did in Batch files created in dos?. Is there a way to use Variables so that the script will be smaller and it can read what month it is now and when it's monday and when it's not monday? if you know how can you give me some examples?

thank you

Hey :)

This should work..

<script language="JavaScript" type="text/JavaScript">
var myDate = new Date() //change for testing - e.g. new Date("Aug 17 2002"), new Date("Nov 21 2002") etc.
//-------------------------------------------------------------------------------------------------------
var j="Jan 1 "+myDate.getYear();j=new Date(j)
n=Math.floor(((myDate.getTime()-j.getTime())/86400000+j.getDay())/7)
m=myDate.getDay()!=1?"ITS NOT MONDAY OLD PICTURE":"MONDAY"
//-------------------------------------------------------------------------------------------------------
document.write("<p align='center'>"+m+"</p><div align='center'><img src='mon"+n+".JPG'></div>")
</script>

Basically, you would need an image for every Monday of the year (i.e. up to 52). This script then checks how many Mondays have past up to the current date - and then writes the image source respectively (i.e. for today - it would write ...src=mon30.jpg, and on the 5th of August ..src=mon31.jpg). Do you follow? It also will write "MONDAY" and "ITS NOT MONDAY OLD" depending on the day of the week...

Hope that helps - let me know if you need more explaination
