hello, i would like to change all the form buttons of my XOOPS web site. I saw that they were built like this (in include/storyform.inc.php) :

$button_tray->addElement(new XoopsFormButton('', 'post', _NW_POST, 'submit'));

what i would like to do is changing every "submit" by "image".
something like this =>
$button_tray->addElement(new XoopsFormButton('', 'post', _NW_POST, 'image', src='post.gif'));

can someone tell me how to change this.

thx for your help
