Datepicker icon aligned too high??

Datepicker icon aligned too high??

Hi Folks

My calendar icon is aligned too high next to my text field (by only a few pix). It is pushing up the height of the 
td. By the way its a 16px png.
I want it to align exactly with the text field. Any ideas.

Code below and screenshot attached;

<td> 
<input type="text" class="datepicker" name="fye_date" id="fye_date" readonly="true"> <!--- jQuery datepicker ---> <script type="text/javascript"> //$(".datepicker").datepicker({dateFormat: 'dd-M-yy'}); $(function() { $(".datepicker").datepicker({ dateFormat: 'dd-M-yy', firstDay: 1, changeMonth: true, changeYear: true, //showButtonPanel: true, showOn: 'both', buttonImage: 'application/images/calendar_icon.png', buttonImageOnly: true }); }); </script>
</td>

Thanks folks

Ian
