Hi I'm seeking a little java script help, I was hoping to get the total no. of images in a specific directory and put it in a variable named "j" so that I can cycle a slideshow properly, anyone got any ideas of how I might be able to do this, please? 
I've already built a php image uploader which then creates a .js file listing the images and the id no's so that the slide show is easily updatable. Any help would be much appreciated

var image2=new Image()
image2.src="sero.jpg"
var image3=new Image()
image3.src="expo013.jpg"

if (!document.images)

whichimage=step
if (step<j) // if below last image keep cycling through
step++
else // otherwise start at the beginning again.

setTimeout("slideit()",2800) // almost three seconds inbetween each image
}
slideit()
function slidelink(){
window.location=eval("image"+whichimage+".src")
}
