new window

Do you know of a module that displays an image for links that open new windows? We're using External Links, but it uses a background image for this via CSS. To my knowledge, screen readers don't see background images. Also, the background image doesn't allow for alternate text.

According to the accessibility gurus at WebAIM, "users ought to be alerted when the link does not open in the current window or frame. The accessibility issue is that some users can get confused with the new windows." http://webaim.org/techniques/hypertext/hypertext_links#new_window
