Some time ago images (and video embeds) in my blog's feed (both feedburner & default wordpress feeds) stopped working.. I've checked/tried everything: .htaccess file, robots.txt, feedburner settings, wordpress settings and disabled any plugin that deals with feeds. Still no luck.

Then I've noticed in feedburner's "XML Source" that images have in their src "/?ak_action=api_record_view&id=14342&type=feed".. Could this have that effect?
