Just wanted to point out that this is slightly safer:

<a href="<?php home_url('whatever'); ?>">

Not necessarily the best way, but
content_url('uploads/2012/01/cover.jpg'); would give you that. When to
use content_url() depends on the context though.

*Ideally*, something in the /uploads dir happened through the media
uploader, and you'd get the exact URL for the attachment using the
post_id for the attachment and something like wp_get_attachment_url().
Again, this depends entirely on context. More information is needed to
give a proper response.
