hyperlink trouble

Customer Quote:

I want my image to redirect to another address, for example: http://example.net”

Except when i click on the link, the address includes my own domain and the link becomes:

http://blackops.codintelligence.com/”http://example.net”

my html code is this:

<a href="//example.net”"><img src="http://blackops.codintelligence.com/wp-content/uploads/2010/10/ordernow.jpg" alt="" title="" width="900" height="737" class="aligncenter size-full wp-image-110" /></a>
