Outlook 2007 hyperlink and text-indent

Basically I am trying to hide the text from t开发者_运维知识库he hyperlink. I've tried pretty much everything so far, however with not luck on Outlook 2007.

<a href="http://www.dominos.co.uk/" height="35" width="155" style="margin: 0 auto; display: block;
width: 155px; height: 35px; text-indent: -1999px; overflow: hidden; filter:alpha(opacity=0);
zoom: 1;"><font size="35">DOMINOS</font></a>

Display and overflow are on the Unsupported list for Outlook 2007. I think in the neutered state of the rendering engine on outlook 2007+, it is safe to say that filter is also not a supported property. See the MSDN on Word 2007 HTML and CSS Rendering Capabilities in Outlook2007, http://msdn.com/en-us/library/aa338201(v=office.12).aspx, and code like it's 1989.

What I was getting at is without the display block the text-indent won't work on the anchor tag as it is an inline element.
