Refresh image size of child div to never exceed parent div

Question

I want to determine the size of the image when it is placed in the main image, and if it is above a certain height, make the image a certain height. I have problems with this because now it seems that it only detects the first image and currently does not respond when I select another image by clicking on the thumbnail.

All images placed in the main image area should be centered.

javascript is not working, but I think I hope in the right direction.

$('.thumb-box').click(function() {

  $(this).parent('.main-image').attr('src', '.thumb-box > img').fadeIn();

});

//Resize image
  $('.main-image').each(function() {
  if ($(this).height() > 550) { $(this).addClass('higher-than-max'); }
  else if ($(this).height() <= 550) {$(this).addClass('not-higher-than-max');}
});

.parent{
  border:1px solid purple;
  height:100%;
  width:80%;
  float:Right;
}
.child{
  border:1px solid red;
  height:100%;
  background:gray;
  text-align:center;
}
.child-img{
display:inline-block;
max-width:100%;
margin:0 auto;
}
.image-wrapper{
  width:100%;
  background:orange;
}
.thumbnails img{
width:auto;
height:100%;
width:100%;
}
.thumbnails{
  width:100px;
  height:100px;
  
}
.thumb-box{
  height:40%;
  width:40%;
  display:inline-block;
  background:red;
}
.higher-than-max{
  max-height:500px;
  width:auto;
}
.not-higher-than-max{
  max-height:100%;
  width:auto;
}

<div class="parent">
  <div class="child">
  <div class="image-wrapper">
    <img src="http://vignette2.wikia.nocookie.net/pokemon/images/b/b1/025Pikachu_XY_anime_3.png/revision/latest?cb=20140902050035" alt="374x333" class="main-image">

.click():

• .main-image thumb-box, parents() ⁽¹⁾ parent() , parents('.image-wrapper').find('.main-image').
• .attr('src', '.thumb-box > img') ".thumb-box > img" src , .thumb-box src.

JS Fiddle 1

$('.thumb-box').click(function() {

  // grab the src of the image nested in the just clicked tumb-box
  var theSRC = $(this).find('img').attr('src');
  // using parents() we grab the .image-wrapper, then the main-image nested inside it
  // and inject the stored src value of the thumb-box image into the main-image source
  $(this).parents('.image-wrapper').find('.main-image').attr('src', theSRC).fadeIn();

});
