Styling Content Loaded from Ajax

Styling Content Loaded from Ajax

I've created code that loads multiple images from an html file using Ajax into a div in another html file.  I have code written to enlarge the image using mouseover() and make it smaller using mouseout().  This code worked prior to removing the images and loading them through Ajax.  I would also like to style the image so they're all the same size before the mouseover/mouseout functions are executed.  Any ideas on how to accomplish this?  Here is my code from the main html file.
 
<!DOCTYPE html>
<html lang='en'>
<head>
 <meta charset='utf-8'>
 <title>Music Stars</title>
  
 <!-- style images here-->
 <style>
  .resize {
   height: 150;
   width: 100;
  }
  
 </style> 
 
 <!-- pulls the ajax file -->
 <script language="JavaScript" type="text/javascript" src="ajax.js"></script>
 
 
 <script src="jquery.js"></script>
 <script>
  $(document).ready(function() {
   //$('.hhImages').add('img').css("height", "150", "width", "100");
   
   //---- CODE TO LOAD HIP HOP ARTISTS ----
   $('#hipHop .button').click(function() {
    $('.hhImages').load('finalProjectImgHipHop.html');
    $(".hhImages").toggle();
    
   });
   
   //---- CODE TO LOAD ROCK ARTISTS ----
   $('#pop .button').click(function() {
    $('.popImages').load('finalProjectImgPop.html');
    $(".popImages").toggle();
   });
   
   //---- CODE TO LOAD POP ARTISTS ----
   $('#rock .button').click(function() {
    $('.rockImages').load('finalProjectImgRock.html img');
    $(".rockImages").toggle();
   });
   
   //---- CODE TO ENLARGE IMAGES ON MOUSEOVER ----
   $("img").mouseover(function(){
    $(this).css("height", "400", "width", "200");
   });













































   $("img").mouseout(function(){
    $(this).css("height", "150", "width", "100");
   });
  });
  
 </script>
</head>
 
<body> 
 
 <!-- code for topic -->
 <div id="intro"><h1>Celebrities in Music</h1>
  <p>
   The following artists are popular in Rock, Pop and Hip-Hop music genres.
   Click on the button of the corresponding genre to view or hide the images.
  </p>
 </div>
  
 <div class="artists">
  <!-- code for HIP HOP sub-topics -->
