Use images in navigation

[Cairan]

Hey. After playing around with the navigation for a bit I was curious if it is possible to use images instead of titles in the navigation.
 

$homepage = $pages->get("/"); 
$children = $homepage->children("limit=21");
$children->prepend($homepage);

foreach($children as $child) {
        $class = $child === $page->rootParent ? " class='on'" : '';
	echo "<li><a$class href='{$child->url}'>{$child->nav_image}</a></li>";
}

At the moment I have this which ofcourse won't work. Is there a way to display $child->nav_image as a image?

Hi Cairan and welcome to PW.

Of course: 

<img src="{$child->nav_image->url}" />

Although depending on your image settings, you may need to use: $child->nav_image->first()->url

Have a read of: http://processwire.com/api/fieldtypes/images/
