Anti-anti-hotlinking for Wordpress

Our site uses several RSS feeds for producing content on a Wordpress blog. We used to use RSS for 1 site, but changed to a custom word-press wrapper that runs hourly via a cronjob. Unfortunately we have been blocked to leech images from that site (hotlinking) and now need a new way to still be able to use their images. Possible solutions: * Store their images on our local server by editing the wordpress-wrapper to not only get their content in our databases, but also their images on our server. * Link to their image via another domain, so will not be recognized by their anti-hotlinking .htaccess that filters based on our domain.
