Jquery Image size manipulation

I am trying to make a jQuery image viewing gallery so you hover over the image and it becomes the background the gal (gallery) div.

$(document).ready(function(){
    $("#img1").hover(function(){
        var img1 = document.getElementById("gal");
        gal.style.background="url(images/img1.png), black";
    });
    $("#img1").mouseout(function(){
        gal.style.background="none";
    });
});
$(document).ready(function(){
    $("#img2").hover(function(){
        var img2 = document.getElementById("gal");
        gal.style.background="url(images/img2.png), black";
    });
    $( "#img2" ).mouseout(function(){
         gal.style.background="none";
    });
});

The html code 

        <section>       
 <h1> Images</h1>
 <h3> Photos </h3>
 <div id="gal">
 </div>
 <img id="img" src="images/img1.png" width="100px" height="100px"/>
 <img id="img" src="images/img2.png" width="100px" height="100px"/>

    </section>

This is my code and it works perfectly fine but using this code I am required to input each div individually.

Is there a way so when you hover over an image it knows what image that is and it makes the div background equal that? Thank you for your help.

P.S. I am quite new to JavaScript.

Try this:

   $(document).ready(function(){
   var gal = $("#gal"); //Avoid repeated traverse

   $("img").hover(function(){
     gal.css("background",'url(' + $(this).attr('src') + ')');  
     //Assuming you want to set current image as background image
    });

   $( "img" ).mouseout(function(){
      gal.css("background","none");  
   });
  });

This is basic mechanism. You may have to change selector and path as per your requirement.

You can assign the same class to each img. Example : 

<img class="img-class" src="img1" />
<img class="img-class" src="img2" />
<img class="img-class" src="img3" />
<img class="img-class" src="img4" />

$(document).ready(function(){
       var gal = $("#gal"); //Avoid repeated traverse
      //Assign class so that this doesnt happen on other images in the html
       $(".img-class").hover(function(){
         gal.css("background",$(this).attr('src'));  
         //set current image as background
        });

       $( ".img-class" ).mouseout(function(){
          gal.css("background","none");  
       });
    });

This should work.
