I am trying to make sure that my carousel size stay the same in terms of height. I am using different images and i understand the image size are different but not sure how to control the height of the image. I want my carousel height stay the same regardless of the image size so how can i control that? here is the code i am using:

```
<div id="myCarousel" class="carousel slide"  data-ride="carousel" >
    <!-- Indicators -->
    <ol class="carousel-indicators">
      <li data-target="#myCarousel" data-slide-to="0" class="active"></li>
      <li data-target="#myCarousel" data-slide-to="1"></li>
      <li data-target="#myCarousel" data-slide-to="2"></li>
      <li data-target="#myCarousel" data-slide-to="3"></li>
    </ol>

    <!-- Wrapper for slides -->
    <div class="carousel-inner" role="listbox">
      <div class="item active">
        <%--<img src="img_chania.jpg" alt="Chania" width="460" height="345">--%>
          <img src="img/sleep1.jpg" alt="Chania" width="460" height="345" />
          <div class="carousel-caption">
              <h1>Example headline.</h1>
              <p>this is test </p>
         </div>
      </div>

      <div class="item">
       <%-- <img src="img_chania2.jpg" alt="Chania" width="460" height="345">--%>
          <img src="img/image5.jpg" alt="Chania" width="460" height="345"/>

      </div>

      <div class="item">
        <%--<img src="img_flower.jpg" alt="Flower" width="460" height="345">--%>
          <img src="img/nature3.jpg" alt="Chania" width="460" height="145" />
          <div class="carousel-caption">
              <h1>Example headline.</h1>
              <p>this is test </p>
         </div>
      </div>

      <div class="item">
        <%--<img src="img_flower2.jpg" alt="Flower" width="460" height="345">--%>
          <img src="img/nature2.jpg" alt="Chania" width="460" height="245"/>
      </div>
    </div>

    <!-- Left and right controls -->
    <a class="left carousel-control" href="#myCarousel" role="button" data-slide="prev">
      <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
      <span class="sr-only">Previous</span>
    </a>
    <a class="right carousel-control" href="#myCarousel" role="button" data-slide="next">
      <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
      <span class="sr-only">Next</span>
    </a>
  </div>
