Placemark image being stretched on Google Maps API application

Has anyone else experience a custom placemark being vertically stretched and found a solution to it?

Example: http://www.mattpotts.com/so-stretched.png

And this is the code I have:

var blueIcon = new GIcon(G_DEFAULT_ICON);
blueIcon.image = "images/beer-24x24.开发者_开发问答png";
var marker = new GMarker(point, {draggable:true, icon:blueIcon})

Sounds like you want to set:

blueIcon.size = new GSize(24, 24);

along with customizing other properties of GIcon. The stretching is occurring because G_DEFAULT_ICON is a typical Maps pin, and is something like 20x32.
