How to get location/URL of image in assets folder?

Sorry for the newbie question.

If I put an image in my themes folder at this location:

themes/dashboard/assets/img/mc_vs_ax_accpt_h_038_png.png

How then do I refer to this image in my view file, such that I am referring to the image that Yii transfers into the assets folder?

Thanks

You can use <?php echo Yii::app()->theme->baseUrl; ?>/assets/img/mc_vs_ax_accpt_h_038_png.png
