Hi from France to all ;)

I search for a script to make drop images on the whole screen of the navigator ( ie/opera/firefox/netscape ) which work fine on my personal website. ( see my profile for a link )
This one is build with pragmax-smf-coppermine.

I tried somes scripts avaibles on dynamicdrive and elsewhere but there is an incompatibilty with my shoutbox ( it's froze the scroll of the messages ) or when it's work fine with the shoutbox, the script is not supported by all navigators.

Finnaly i found this one which display ballons and satisfy me :



// Float Up Drifter - JavaScript
// Configure below - change number of images to render
var no = 10;
// Configure speed below
var speed = 20; // The smaller the number, the faster the movement
var floatr = new Array();
// Your images location
floatr[0] = "/balloon0.gif"
floatr[1] = "/balloon1.gif"
floatr[2] = "/balloon2.gif"
floatr[3] = "/balloon3.gif"
floatr[4] = "/balloon4.gif"
floatr[5] = "/balloon5.gif"
floatr[6] = "/balloon6.gif"
floatr[7] = "/balloon7.gif"

But i have a matter, i want to reverse the scroll of the images :
Actually it's start from the bottom to the header.
I want to make start from the header to the bottom ...

I tried some things but, as i have no knowledge in javascripts, i am not able to do this. It's certainly simple for you but not for me... :o

So, is someone can do the modifications in the code for me, please ...

Awaiting your response...
Sincerly.
