Get Current Theme Path

Hi guys just wondering the code to retrieve the current theme path?
doing some styling and wanted to add a logo image like so

<img src="<%=GET CURRENT THEME PATH%>/images/logo.png" alt="<CURRENT SITE TITLE>"/>

SettingManager.GetSettingValue("Display.PublicStoreTheme")

This will return current theme name and it will be the theme folder name.

thanks so very much!

is there any doco on this stuff? ie does the user guide contain it? or best place to ask is the forum?

User guide does not contain programming stuff. Better ask in the forum.
