hello and good afternoon :)

I have spent hours looking around for a script that would make image fall/float from the top of the web page to the bottom but I have had no luck. Any ideas where I might be able to find something like that? The ones that I have found only float down on the top section of the screen. Any suggestions would be greatly appreciated. Thanks a lot!!

You could edit the script you found to have the images float to the bottom from the top.

thanky you havik for trying to help me but I am just not sure where it would be that I would put what you told me to put the script I found is this:

Can I change this somehow? Any thoughts or suggestions

Ok, having taken a look at the script I understand what exactly you want done. The script drops images from the top of the browser screen to the bottom of the browser screen. What you would like is a script that drops images from the top of the window screen to the bottom of the window screen. I hate to inform you but you cannot get this effect with javascript, nor any web language (that I'm aware of) since any sections outside the browser screen cannot be accessed.

Actually what I would like the script to do is to have the image fall from the top of the browser window all the way to the bottom. With the script that I have it only falls 1/4 of the way then disappears. Then it starts over again.

The images do drop from the top of the browser screen to the bottom, however if your web page is larger than the screen, then the images will not drop past a certain point.
Here is how the script works:

First it determines the browser screen width and height and stores these values. The script then operates (drops the images) only within the bounds of these values.

If your webpage's height is larger than the height of the browser screen, then the scroll bar will be active (obvious). All the sections below (when you scroll down), are outside the bounds of the script, so that's why the images do not drop past that point.

If you want the images to continue to drop, while you scroll, then some tracking of the scrolling needs to take place. I will take a look at this and post my findings.

FYI - The script creates "instances" of image. The way I set this up, each instance is given parameters from which it will drop. This means that while you scroll down, you will notice that some of the images will disappear before reaching the bottom. Don't worry, as new instances are being created which will drop to the bottom.
