During some redesign projects it’s handy to have the images (other media) rendered, but sometimes it could be a struggle to download from specific paths.
For WordPress sites I use the following htaccess rule:
RedirectMatch 301 /wp-content/uploads/(.*)$ http://www.example.com/wp-content/uploads/$1
Than for other, custom stuff:
RedirectMatch 301 /media/(.*)$ http://www.example.com/media/$1
