You can delete the link to an attachment from a document, topic frame, or bubble text at any time. For example, you might decide that an attachment linked at the fourth frame of a topic should be linked at the sixth frame instead. In this case, you cannot just change the link target; you need to completely remove the link from the fourth frame. When you delete the link to an attachment, you are not deleting it; you are simply removing the link. The attachment is still in the Library and available for use.
You can delete links to attachments from the Outline Editor (concepts only) or from the Topic Editor (topic concepts and frame and bubble text links).
