Missing images

Hi.

If you look in the right widget area you will see 2 images.
http://couragetotransform.com/

1) Book image in optin area
2) Accreditation images below that.

However if you click on any other link: i.e. FAQ, About Sherri etc... the images are missing.

In Accreditation area I used this html:
<a href="http://www.couragetotransform/"><img src="images/symbols.png" alt="" /></a>

Is this incorrect?

 

I fixed issued by showing entire path.
