[development] Showing SWF file in content

I'm working on a draft of postcards sent between users of the site and notices to each party for each shipment or read receipt, but now they ask me when viewing the content,, do not load the image, but an SWF file . I've added with FielField the form to load the SWF at the time of the creation of content to send, but do not know how to make it appear when viewing this, because CCK generate it as an image. I can give some suggestion about it? thanks in advance
