How to find path to active template files?

I am looking for the code that will get me the path to the active template files so i can include these files in some custom code.

For example. I have an image in my custom template images dir. What is the zen code to this image?

Thanks

Kw,
src="your_template/images/the image name here.jpg"

Thanks, but that isn't quite what I'm looking for. I don't want to hardcode my template name.

I'm looking more alone this line:

HTTP_SERVER . DIR_WS_TEMPLATE . ????? . '/images/myimage.jpg';

OK, I found what I was looking for. Here is how one would zen code the path to the active templates stylesheet.css.

echo $template->get_template_dir('',DIR_WS_TEMPLATE, $current_page_base,'css').'/stylesheet.css';
