Question : mailto isn't working on my image map??

Hi There,
On this site here:
http://abridesign.une.edu.au/index.php?option=com_content&view=article&id=48&Itemid=59

I have an image for the main content, and if you hover over the email address it is supposed to have a mailto: ref for them.

Its an image map with a hot spot, but you can see when you try to click on the email, its all wrong.

Can someone help me fix this up please, and explain why its happening this way?

You should define all the elements of the border to make sure you get what you want (@TheQuietShadow - that didn't work for me... it's missing the border-style) eg

<img src='image.jpg' alt='' style='border:20px solid red;'/>

or adding to @TheQuietShadow's version

<img src='image.jpg' alt='' style='border-width:20px;border-style:solid; border-color:red;'/>
