WordPress creates an attachment page for any images uploaded through the post editor and "attached" to that post. After migrating a site, those attachment pages no longer exist, and we now have around 1000 links pointed at 404's.
So, I was looking to find a way to do a redirect for any url that has /attachement/ in it's string and then push that url back up one level (which happens to be the post page). so for instance:
http://mysite.com/2012/news/blog-post-title/attachment/image-page/ (which doesnt exist) will go to http://mysite.com/2012/news/blog-post-title/ (which does exist).
Along with redirecting up one level, I also need to remove anything after /attachment/ (in this case the "image-page."
Thanks in advance
