Thanks Haven this code worked!
In addition to this, do you have a code to change the image on mouseover?
I have tried this, but to no avail:
<script type="text/javascript">
$(document).ready(function(){
setTimeout(function(){
$('button.mktoButton[type=submit]').after('<img src="http://go.exinda.com/rs/exinda2/images/getthewp_orange.png"
onmouseover="http://go.exinda.com/rs/exinda2/images/getthewp_green.png'"
onmouseout="this.src='http://go.exinda.com/rs/exinda2/images/getthewp_orange.png'" style="cursor:pointer" class="myOwnButton"/>');
$('img.myOwnButton').click(function(){
$('button.mktoButton[type=submit]').click();
});
},2000)
});
</script>
