How to reuse attachments from one post in another post?

I made a post at http://androidforums.com/bionic-all...access-via-local-prop-method.html#post3703527 and I then duplicated the post in the original thread that caused this thread to appear: http://androidforums.com/bionic-all...oot-after-5-8-894-broke-root.html#post3703577

In the second linked thread, the attachments do not show as thumbnails, but as links - how can I go about fixing that (short of re-uploading the file)?

Spoiler

I also want to make a third post (if it does not already exist) in the FAQs about how to do this so folks will know....

 

I thought about doing that. I just don't want five copies of the same file on the server when one will do....
