Googlemaps icon not transparent

Please have a look at this page. You’ll see a google map there, created with [url=]this jQuery plugin. Although I’ve used the plugin on several occasions without any trouble, this time the map’s .png icon/marker cannot be made transparent.

I’ve tried several things (removing my reset.css file, adding a js png- transparency fix, fiddling with the plugin options) but nothing works…

Thanks for any help you can provide!

Simple yet brilliant. (: Fixed!
Thanks dogFang!

#main img {background:transparent;}
