The problem with hard coding a link like this is that you are going to mess up your SEO. There should be only ONE path to your store, ever, and that link should be
www.yourdomain.com
In my opinion, you should hard code this image link to <a href="/"> and then let your htaccess do the rest. This assumes your htaccess takes your customer where you want...
If you have a bunch of inbound links (some to
www.domain.com, some to
www.domain.com/store/home.php, etc.) the search engines (especially google) will share page rank betwen the pages -- they are not identical... and you risk duplicate content issus.
Be consistemt in your links and you won't have these issues.
