I made a simple bit of code to randomly pick and display a picture every few minutes, for my windows desktop, as seen here:



function background()
{
with(Math)
{
var background = (abs(round(random()*10000)))
}
background = background % 2;
background +=1;
element.runtimeStyle.background = "url("+background+".jpg) fixed";
setTimeout( "window.location.reload()", 300000 );
}


Now, that's all very well, but it's a bit inconvenient, since I have to number all my files 1,2,3, and adjust the code everytime I aquire a new picture.

It's been several years since I've done any type of programming, but is there a way I can load the files, for a directory (and possibly the sub-directories) into a Dynamic Array, and get the length of the Array, and how would I do it?

try something like



import java.io.*

...

File dir = new File("images"); // Your image directory
File[] files = dir.listFiles(); // You'll need to check to make sure the file object isn't a directory, see javadocs for java.io.File


Also you can make another class that implements FilenameFilter or FileFilter and pass a filter into listFiles or list.

hope this helps.

Thanks, it's helped me a bit, I'm still very rusty, but it should take me long to get back into the swing of things.
