Bringing my External S3 Images Into Discourse

Hi Guys

I recently imported my old bbpress forum and topics into my development discourse site. Many of my posts contain links to images that are hosted in one of my S3 buckets. Is there a way I can get these images into discourse rather than being loaded directly from my S3 bucket?

I was hoping this setting in the admin section would do the job when I imported the posts, but it didn’t.
