Changing a style adding a link

Changing a style adding a link

Currently on our website we have a products page.  It uses default text links if the product is in stock, or if the products has options to choose from.  If the product is out of stock then there is no link displayed.  I have some jquery that changes the code so that the text links show up as images.  However what I would like to do is if the item is out of stock to show another image.  

The way it works is that a style tag gets changed to hidden if it is out of stock so I'd have to change that style tag to unhide that.  Soooo this is the code I'm using

$(function(){
      $('.ProductActionAdd style:contains("none")').html('<img src="imagesource"/>')
     $('.ProductActionAdd').removeStyle('display');
});
it doesn't work however I'm extremely new to jquery.  Not sure at all what I'm missing.
