I have a function which loops through 28 images.

The first images are `1234jd01.jpg` and then `1234jd02.jpg` all the way to `09.jpg`

After the loop has gone from `01` to `09` it should go to `10`, `12` and all the way up `28` and then loop back.

However my code just does `1,2,4 - 9` and then `10, 11` which works.

**Can I add a `0` to the first set if it is a single digit and then stop at 28? So the first block of images is not showing as missing?**

jsFiddle is: <http://jsfiddle.net/khaleelm/Vv2u3/2/>

My code is

```
$(function () {
    var i = 01;
    var interval = setInterval(function () {
        jQuery('.animationMax img').attr({
            src: 'http://jdsports.scene7.com/is/image/JDSports/127932jd' + i + '?hei=255&amp;wid=427&amp;resmode=sharp&amp;op_usm=1.1,0.5,0,0&amp;defaultImage=JDSports/sizeImageMissing'
        });
        i++;
        if (i === 28) i = 01; //38 images has been shown, stop the interval
    }, 100);
});

```
