sure,

</script>
function resizeImage() {
  document.getElementById('img1').width =  document.getElementById('td1').offsetWidth
}
<script>



  <td id='td1'>
  <img id='img1' src='/images/whatever.gif'>

better yet here's a working test I used.. obviously you won't have my image but you can replace it with yours

<html>
<head>
<script language="javascript" type="text/javascript">
function resizeImage() {
  document.getElementById('img1').width =  document.getElementById('td1').offsetWidth
}
</script>

</head>

<body onLoad="resizeImage()">


<table width="183"  border="0" cellspacing="0" cellpadding="0">
  <tr>
    <td id='td1'><img id='img1' src="logo2.gif" width="5" height="50"></td>
  </tr>
  <tr>
    <td></td>
  </tr>
</table>  

</body>
</html>
 
 
BUT THE ABOVE CODE works if there is one image and TD . I am generating images and TD dynamically. How should I go about doing this.

Please guide me.

Maybe like this ...

function resizeOneImage(imgname, tdid)
 {
  document.getElementById(imgname).width =  document.getElementById(tdid).offsetWidth
}

function getElementsById(imgname, id)
{
  var inc = 0;
  var alltags = document.all ? document.all : document.getElementsByTagName("*");
  for (i = 1; i < alltags.length; i++)
    if (alltags[i].id == id)
      reziseOneImage(imgname, id);
}
<body onload="getElementsById('img1', 'td1');" >
....
<td id='td1'><img id='img1' src="logo1.gif" width="5" height="50"></td>
<td id='td1'><img id='img1' src="logo2.gif" width="5" height="50"></td>
<td id='td1'><img id='img1' src="something_else.gif" width="5" height="50"></td>
....
</body>

Setting the width and height of the image to 100% means it will stretch and shrink to fit the table cell it occupies. As the user resizes their browser window your picture will resize automatically.

I tried the below code

<html>
<HEAD>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<SCRIPT type="text/javascript">
<!--
function resizeOneImage(imgname, tdid)
{
     document.getElementById(imgname).width =  document.getElementById(tdid).offsetWidth;
}
var fields = new Array();     // Global array for the field objects we want
////////////////////////////////////////////////
// Resize all images with a specific id
//
function resizeImages(id)
{
     var inc = 0;
     var alltags = document.all ? document.all : document.getElementsByTagName("*");
     for (i = 1; i < alltags.length; i++)
     {
          if (alltags[i].id == id)
          {
               fields[inc++] = alltags[i];     // Save the object in the array
          }
     }
     for (i = 0; i < fields.length; i++)    
     {
          if (fields[i].name)
               resizeOneImage(fields[i].name, id);
     }
     return inc;
}
//-->
</SCRIPT>
</head>
<BODY onLoad="resizeImages('b');">
<table width="280"  border="0" cellspacing="0" cellpadding="0">
  <tr>
    <td id="b"><img id='b' name="img1" src="imgage1.gif"></td>
    <td id="b"><img id='b' name="img2" src="imgage2.gif"></td>
    <td id="b"><img id='b' name="img3" src="other.gif"></td>
  </tr>
</table>
</body>
</html>


THE IMAGE IS SMALL IN THE FIRST CELL SLOWLY IT INCREASSES IN THE LAST CELL IT FITS THE TD
I recommend a split between peakpeak and myself :)
