Ofcourse it should be looking like that, the problem is that the image links aren't working so we have no way of restoring those. Unless someone somewhere actually saved the image files.
-- Edit --
Nevermind, i found the images online somewhere and put them in this zip for you. Lucky!

Upload those two files to your public/style_images/(skin_image_folder) . Now change the CSS back to what it used to be with the background urls there but change exactly this part:

and exactly this part:
http://img59.imageshack.us/img59/9923
to:
{style_images_url}
As a general tip, the way this mod implemented those images was wrong - it should have let you upload them to your skin folder initially to avoid image hosting sites removing them in the first place. A common best practice for your website/forum is to host as much images locally as possible.
