Просто добавьте:
<img src="path/to/your/image_1" alt="image_1" />
<img src="path/to/your/image_2" alt="image_2" />
<img src="path/to/your/image_3" alt="image_3" />
и т.д ...
EDIT:
for(var i = 1 ; i < TOTAL_IMAGES ; i ++ )
{
var img = document.createElement('img');
img.src = "path/to/your/image_" + i;
img.alt = "image number " + i;
document.appendChild(img); // this will append the image to the root element. You might want to use a <div> or something instead.
}
