i have javascript gets images in folder called "pictures/" want code writen can have each div different different images folder tell cant figure out how set up. im knew , appreciate help:

 function displayimage(image) {           document.getelementbyid("img").src = image;            document.getelementbyid("img2").src = image;             document.getelementbyid("img3").src = image;       }        function displaynextimage() {           x = (x == images.length - 1) ? 0 : x + 1;           displayimage(images[x]);                  }        function displaypreviousimage() {           x = (x <= 0) ? images.length - 1 : x - 1;           displayimage(images[x]);                  }        function starttimer() {           setinterval(displaynextimage, 1000);       }        var images = [], x = -1;       images[0] = "pictures/" + "1.jpg";       images[1] = "pictures/" + "2.jpg";       for(var y=2;y<4;y++){       images[y]= "pictures/" + (y+1) + ".jpg";       }

html:

    <div><img id="img" src="pictures/1.jpg">7</div> <div><img id="img2" src="pictures/1.jpg">8</div> <div><img id="img3" src="pictures/1.jpg">9</div>

in displayimage() method pass index of image rather image

and change value of index such should not cause arrayoutofboundindex error

then displayimage() method this

function displayimage(imageindex) {       document.getelementbyid("img").src = images[x];        document.getelementbyid("img2").src = images[x+1];         document.getelementbyid("img3").src = images[x+2];   }
