i.e. I have 18 sections split into 3 columns - after the first nine sections, i'd like to put a break or a line to seperate them
You can do it by customizing module template.
Additionally if the category id = 'nn' i'd like to put a small image rather than the category name.
here is sample code:
<a href="http://www.yoursite.com/blog/0-102" TARGET="_self"><img src="http://your_image_url.jpg" border=0 alt="text if image cannot load"></a>
marked in blue: Direct url to specific category or section
marked in orange - image url
marked in green - alt text. If image cannot load
marked in red - opening in same window.
(_blank= opens in new window)
