New posts/no new posts question
 

Just curious to know if this is possible really, or ideally if anyone knows how to do it :)

Basically this is my forum's homepage...
http://www.communityhq.org/forums/index.php?

Those 6 icons along the top, like this...
http://www.communityhq.org/forums/links/hhq.jpg
link to the different forum sections, but what I'd ideally like is instead of the static icons, I'd like to be able to alternate between 2 versions of them, one if there's new posts in the particular forum section they link to, and one if there isn't. Maybe highlight the small triangles on them or something.

So anyway, be grateful for any help on this :)
