I checked the source code and it's looking here
Code:
<img src="http://www.letsgokings.com/bbs/images/spacer.png" style="width: 0; height: 0; filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='http://www.letsgokings.com/bbs/images/googlemapme/mm_20_blue.png', sizingMethod=scale);" border="0" alt="Team LGK">: Team LGK<br />
I looked in my /bbs/images/googlemapme folder and there IS a file called mm_20_blue.png but they still aren't showing in the legend. Can you see any other problem with that link?
