Re : RSS feeds and Galleries Suggestions
Image: I am not completly sure it is the same problem but a bug was fixed yesterday about the image cache in 1.8 cvs that was replacing inappropriatly the url . Try to update your tiki or try to take away the cache (admin -> général -> Use cache for external images)
RSS: http://tikiwiki.org/tiki-view_forum_thread.php?forumId=4&comments_parentId=12247
It needs to be fixed...
