Christmas Theme help

[Disco_Dave]

Hi Peeps

I wondering if anyone could help me with this? Our last admin guy deleted our Christmas theme last year, I'm going through some old templates and I found it, see below:

/******************************************
Aaron's Snow Effect Script
******************************************/

//Configure below to change URL path to the snow image
var snowsrc="http://www.nirc.org.uk/snow.gif"
// Configure below to change number of snow to render
var no = 0;
// Configure whether snow should disappear after x seconds (0=never):
var hidesnowtime = 25;
// Configure how much snow should drop down before fading ("windowheight" or "pageheight")
var snowdistance = "windowheight";
///////////Stop Config//////////////////////////////////
var ie4up = (document.all) ? 1 : 0;

return (document.compatMode && document.compatMode!="BackCompat")? document.documentElement : document.body
}
var dx, xp, yp; // coordinate and position variables
var am, stx, sty; // amplitude and step variables
var i, doc_width = 800, doc_height = 600;

if (ns6up) {
doc_width = self.innerWidth;
doc_height = self.innerHeight;
} else if (ie4up) {
doc_width = iecompattest().clientWidth;
doc_height = iecompattest().clientHeight;
}
dx = new Array();

snowsrc=(snowsrc.indexOf("dynamicdrive.com")!=-1)? "snow.gif" : snowsrc
for (i = 0; i < no; ++ i) {
dx[i] = 0; // set coordinate variables
xp[i] = Math.random()*(doc_width-50); // set position variables
yp[i] = Math.random()*doc_height;

for (i = 0; i < no; ++ i) { // iterate for every dot
yp[i] += sty[i];
if (yp[i] > doc_height-50) {

contenttype: ['inline'] //content setting ['inline'] or ['ajax', 'path_to_external_file']
})
</script>

I'm in no way a coder or a graphic designer, but I'd like to be able to get this back up and running for Chrimbo, so If anyone could help me that would be great.

Regards,
Dave

That isnt Aaron's snow effect as listed at the top of your thread. It was swiped from Dynamic Drive and he removed the copyright to try and authenticate it as his.

Go here: http://www.dynamicdrive.com/dynamicindex3/snow.htm

All instructions and code are free to use as long as copyright is intact.

Simples!

Thanks Robbiez, and cheers for clearing something's up for me.

Cheers
Dave
