I want to centre an image within a div (height = 200px, width = 200px)
The image is 175px wide, height is dynamic
Horizontally aligning is not an issue, but vertical alignment is not working.

I don't want to use a background-image

The solution must work in IE7&8   (so not a CSS3 solution)

There are lots of samples in EE but I can't get any to work in IE7 with images that have dynamic heights, without setting the background-image

Try using a position relative div with an absolute div inside.  http://jsbin.com/gogum/1/edit?html,css,output  

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>JS Bin</title>
</head>
<body>
 
  <div class="outer">
    <div class="inner">
      <img src="" width="200" height="200">  
    </div>
</div>
   
</body>
</html>

Open in new window

.outer{position:relative;width:400px;height:400px;background-color:green;}

.inner{position:absolute;bottom:100px;}

img{background-color:red;}

Open in new window

I was thinking of from the bottom...been a long night...

This uses jquery 1.1 and will work with ie.  You can type any height in the with to simulate what will happen.  Just click the "Run with js" after you change the hight (if you test in jsbin).  

<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
  <meta charset="utf-8">
  <title>JS Bin</title>
</head>
<body>
 
  <div class="outer">
      <img src="" width="175" height="300">  

</div>
   
</body>
</html>

Open in new window

.outer{width:400px;height:400px;background-color:green;text-align:center;}



img{background-color:red;}

Open in new window

$(function() {
  var h = $('.outer img').height();
  var m = (400-h)/2;
  
  $('.outer img').css('margin-top',m);
});

Open in new window

This of course assumes that the image will not be taller then your 200px outer div.

Ok, this time I made the outer 200X200  

.outer{width:200px;height:200px;background-color:green;text-align:center;}
img{background-color:red;}

Open in new window

$(function() {
  var h = $('.outer img').height();
  var m = (200-h)/2;
  
  $('.outer img').css('margin-top',m);
});

Open in new window
