jQuery Set Image TITLE from ALT Tag

jQuery Code Snippet to get the alt tags of each image and set the title tag so it is the same as the alt tag. Could be useful to improve SEO for the web page and added support for browsers such as Firefox that utilise image title tags.

jQuery(document).ready(function($) {
    $("img:not([title])").each(function() {
            if($(this).attr("alt") != '') $(this).parent().attr("title", $(this).attr("alt"))
            else $(this).parent().attr("title", $(this).attr("src"));
    });
});
