image_url empty

Hi guys,

I am looping my events categories in a custom template as so:

foreach($categories as $category)
{
   $url = $category->image_url;
}

However the $category->image_url is always empty, despite there being an image uploaded and being pulled into the admin.

I have also tried: get_the_post_thumbnail($category->ID, ‘thumbnail’); but neither return anything.

Any ideas?

Thanks,

Dave
