Hi experts..

I'm developing a web using aspx. My web is based on gallery uploading. So i need something like on facebook photo upload. When i upload a folder that contain the image it will automatically create a div with the album name on my page.

below is the code that i used to insert image on div.

JavaScript

//CREATE DIV BOX
   var dvs = document.createElement('div');
   dvs.style.position = "absolute";
   dvs.style.top = Vtop + "px";
   dvs.style.left = Hleft + "px";
   dvs.style.height = "120px"
   dvs.style.width = "100px";
   dvs.style.cursor = "pointer";
   dvs.onclick = function(){CreateFrame(DivID)} ;
   dvs.setAttribute('id',DivID);

JavaScript

//CREATE IMAGES & EMBED IN DIV
   var EbdImg = document.createElement('img');
   EbdImg.setAttribute('src','Web_Images/arrow_down.png');
   EbdImg.setAttribute('width','100%');
   EbdImg.setAttribute('height','100px');
   EbdImg.style.width = "100%"
   dvs.appendChild(EbdImg);

But the problem is, i need to insert random image automatically to the album from the latest folder that i upload and not from the existing folder from directory.
thanks in advance :)

var imgPath = "";
var imageArray = ['t_0001.jpg', 't_0002.jpg', 't_0003.jpg'];

imgPath = 'Gallery/' + DivID + '/thumbs/';

var selectedImg, EbdImg;
while(imageArray.length != 0)
{
selectedImg = getRandomImg();
}
var EbdImg = document.createElement('img');
EbdImg.setAttribute('src', imgPath + selectedImg);
EbdImg.setAttribute('width','100%');
EbdImg.setAttribute('height','100%');
EbdImg.style.width = "100%"
EbdImg.style.borderRadius = "1px";
dvs.appendChild(EbdImg);

imageArray = ['t_0001.jpg', 't_0002.jpg', 't_0003.jpg'];

function getRandomImg(s)
{
var selectedImg, randomImgIndex;
randomImgIndex= Math.floor(Math.random(imageArray.length)*imageArray.length);
selectedImg = imageArray.splice(randomImgIndex,1);
return selectedImg;
}

This is my Output

Assuming you have the list of images. Code goes like this -

JavaScript

var imgPath    = 'Web_Images/',
    imageArray = ['img01.jpg', 'img02.jpg', 'img03.jpg', 'xyz.jpg', 'abc.jpg'];

function getRandomImg(s) {
  var selectedImg, randomImgIndex;
  randomImgIndex= Math.floor(Math.random(imageArray.length)*imageArray.length);
  selectedImg = imageArray.splice(randomImgIndex,1);
  return selectedImg;
}

function createImages() {
  var selectedImg, EbdImg;
  while(imageArray.length != 0) {
    selectedImg = getRandomImg();

    //modify it according to your need
    EbdImg = document.createElement('img');
    EbdImg.src = imgPath + selectedImg;
  }
}

createImages();

Insert random image to div.
