</script>

<div  id="test">
<img alt=''  src='imges/book1.jpg' />
<img alt=''  src='imges/book2.jpg' />
</div>

Answer 1

document.getElementsByTagName('img'); returns a node list not a single element

    var  yourImg =  document.getElementsByTagName('img'); // both img tags in this list
    yourImg[0].style.height = '400px';
    yourImg[0].style.width = '300px';
