I added custom script

wp_enqueue_script('functions', get_bloginfo('template_url') . '/js/functions.js', 'search', null, false);

works great, except

in the functions.js i have

Reset.style.background = "url('../images/searchfield_clear.png') no-repeat top left";

now this used to work before, until changed to pretty permalinks and .htaccess

the folder hierarchy is like:

themename/js themename/images (the images and js folder are in themename folder)

i tried ../images - ./image - /images

normally it should go back 1 level where-ever the js file is located....

i dont want to use full path is there a other way that wordpress can recognize in the javascript file to have the correct path?

currently i am just confused what i am doing wrong
