    You can find all img element of parent div like below

    $(this).find('img') or $(this).children('img')
    

    If you want specific img element you can write like this

    $(this).children('img:nth(n)')  
    // where n is the child place in parent list start from 0 onwards
    

    Your div contain only one img element. So for this below is right

     $(this).find("img").attr("alt")
                      OR
      $(this).children("img").attr("alt")
    

    But if your div contain more img element like below

    <div class="mydiv">
        <img src="test.png" alt="3">
        <img src="test.png" alt="4">
    </div>
    

    then you can't use upper code to find alt value of second img element. So you can try this:

     $(this).find("img:last-child").attr("alt")
                       OR
     $(this).children("img:last-child").attr("alt")
    

    This example shows a general idea that how you can find actual object within parent object. You can use classes to differentiate your child object. That is easy and fun. i.e.

    <div class="mydiv">
        <img class='first' src="test.png" alt="3">
        <img class='second' src="test.png" alt="4">
    </div>
    

    You can do this as below :

     $(this).find(".first").attr("alt")
    

    and more specific as:

     $(this).find("img.first").attr("alt")
    

    You can use find or children as above code. For more visit Children http://api.jquery.com/children/ and Find http://api.jquery.com/find/. See example http://jsfiddle.net/lalitjs/Nx8a6/

    Without knowing the ID of the DIV I think you could select the IMG like this:

    $("#"+$(this).attr("id")+" img:first")

    Ways to refer to a child in jQuery. I summarized it in the following jQuery:

    $(this).find("img"); // any img tag child or grandchild etc...   
    $(this).children("img"); //any img tag child that is direct descendant 
    $(this).find("img:first") //any img tag first child or first grandchild etc...
    $(this).children("img:first") //the first img tag  child that is direct descendant 
    $(this).children("img:nth-child(1)") //the img is first direct descendant child
    $(this).next(); //the img is first direct descendant child

    You can use either of the following methods:

    1 find():

    $(this).find('img');
    

    2 children():

    $(this).children('img');

    jQuery's each is one option:

    <div id="test">
        <img src="testing.png"/>
        <img src="testing1.png"/>
    </div>
    
    $('#test img').each(function(){
        console.log($(this).attr('src'));
    });
