I like it, but it's not generic enough for me.

How about if you did something like this in a post?
<img src="[homeurl]/wp-content/uploads/whatever.jpg" />

[homeurl] is simply replaced with the home url. The shortcode handler
for that is like two lines of code:
function homeurl_shortcode() { return get_option('siteurl'); }
add_shortcode('homeurl', 'homeurl_shortcode');

Or, if you want it more specific, have [homeurl], [contenturl],
[adminurl], etc... Whatever makes sense.
