Any advantage of using forms and links to log out?

Question

I am creating a web application and just working on the logout function (simple unset / meta refresh / redirect code on logout.php session)

Perhaps a simple question (although I hunted for Google to no avail), but is there any use to the exit button on the site from using the form that is sent to logout.php compared to the graphic image of the button with href that links to one page?

Functionally, they both work the same, but is there a potential security issue, etc.

Thanks heaps!
