Add transparency to a Google Marker

Question

I have a marker that looks like the on in this tutorial : http://www.powerhut.co.uk/googlemaps/custom_markers.php

Can I add transparency to this marker ?

I've looked over the net and failed to find something that would help me in this issue. In Bing Maps I can do something like this :

var veCustomIco = new VECustomIconSpecification();
veCustomIco.CustomHTML= "<img src='" + url + "' style='filter: Alpha(opacity=10);-moz-opacity: 0.1;opacity: 0.10;'/>";
pin.SetCustomIcon(veCustomIco);

Thank you.

Answer 1

You can add transparency as you wish as this is a PNG file. PNG files can have transparency. Just edit the image file with photoshop or the like.
