Are you talking about action_replace_with_url? No, it should create
only *one* instance of the attachment. It works by calculating
the SHA-1 hash of the attachment and constructing a file name from
that. If two different attachments hash to the same SHA-1 value,
either you have won the lottery fifty times consecutively, or someone
has broken SHA-1. :-)
If you could post your filter, perhaps I could help figure it out.
