[SOLVED] Using images in Next/Previous Navigation

I would like to use images as links for the next/previous navigation at the bottom of posts. I understand that Atahualpa calls wp_link_pages() to generate the navigation links, and it doesn't look like that function accepts any arg's except string values from the documentation. I can insert an image into the navigation, and it shows up, but I don't understand how to make the image into a link. (Or how to make anything other than %link work, for that matter)

In the options, it says "You can use single and double quotes, and HTML". Can anyone show me an example of the syntax to use something other than %link? I'd be happy with just an "arrow" that functioned as the link if I can't use an image, rather than a text based link.

As of now, anything other than the default %link does not create a link at all, just plain text

Thanks in advance,

Tim
