Can't add a new Ad icon - Is that a bug?

Not sure if this is a bug.  I added a new category in Ads.  Please look at the images below.

I checked the picture link to be sure it's a correct path.  I checked this... http://mysite.com/modules/boonex/ads/templates/base/images/icon/star.php    I see the icon in there and it's working but the icon in Ads is still not showing.  Is this a bug?  

I checked the picture path for "For Sale".  It shows "shopping-cart".  Where the hell is that?  It's not even in boonex Ad nor template folder (i think).  

You are linking to star.php; is that correct?  I don't see a star.php in icons in my ads module.  I would think you would link to an image file.

 Actually i'm linking to star.png... not star.php :P   Yep i tested and the link is working fine but not showing in Ads at all.  Very strange.  I'm still looking.  I don't even know where "shopping-cart" is coming from.  

Edit:  oh sorry.  I guess i wasn't clear.  i added a new star.png for a new category.  

ah im an idiot!  It's NOT a bug.  Just type "star.png"  Don't need to type a long path.  It will read in /modules/boonex/ads/templates/base/images/icons/ 

That's it.
