Boxes.php various images?

[rxsid]

Hi all,

I'm looking to put various images in the various boxes, instead of the little right arrow in all boxes. For example, I would like to put image review.gif in the review box title row in place of the right_arrow.gif image but I'm not really sure where to do that. Right now, I'm thinking it would be set in the includes/classes/boxes.php file, but the infoHeadingBox function has this

$right_arrow = false

in it and I don't see where it's set to true. If it's never true, how is the right_arrow.gif even showing up at all? That's probably an aside, what I'm really wondering is how do I display a review.gif when the review box is being displayed, or say...a whatsnew.gif when the whatsnew box is being displayed?

Thanks!
