An image size and a div size doesn't match - removing-whitespace

Question

(I am making a website by myself and it's the first time. I am adding this writing because my post is mostly code. )
I added an image on the right div 'about_Cell2', but I don't know where the about 1px space comes from..
Please help me..

Answer 1

Try using
<div class="about_Cell2" style="background-image:img/2.jpg"></div>
instead of
<div class="about_Cell2"><img src="img/2.jpg" width="500px" height="650px" alt="baan yang" /></div>
