Nav bar image troubles!

Hi All!
I'm trying to insert some image links into my nav bar. I've put the code into my tpl_header file, and the links themselves work, however the images aren't showing up. (Dreaded box with red X). At first I thought perhaps I hadn't specified the correct path to the images, but I've checked that, and fiddled around with the path (using full path, and using just image file name), but neither option is working. I just can't seem to get the images to show. Can anyone take a look and help me out with this? The page is at http://www.eyecandey.com/cart/index.php
Thanks for any advice you may have - I've been going back and forth with this for a while, and feel like I've read every post in the forum!

Buffalogal

where are your image files? try http://eyecandey.com/cart/images/aboutbutton.jpg and put your image in the image folder. at the moment the url http://eyecandey.com/cart/aboutbutton.jpg means the file should be in http://eyecandey.com/cart/ folder, is it? Cant' see why it shouldn't work.
All the best pots

The image files are located in: /cart/includes/templates/classic/images. I've tried using this entire path, and also using just the filename - neither will work! I just can't figure what I'm doing wrong. Am I supposed to edit another file as well?

Let's see the code you have in the tpl_header.php

Pots, I think I've got it - Thanks so much!!! I copies the images over to the cart/images folder and then changed the reference to full url like you had above and it works!! I've just fixed one for now - will work on the rest when I get home, but thanks again, that seems to have done it!
