Displaying or linking to Flash SWF content

We need to create a link from an image in an exhibit to a Flash interactive (swf). I thought I could do this in HTML, but the WYSIWYG editor is stripping all the HTML out. Is there a way to work around this? Any recommendations or examples of how this may be accomplished?
Thank you,
Scott

Scott,
Have you seen this discussion about doing a similar thing in exhibit pages?

I'm not exactly sure where Erin did this, but I'm hoping we might get him to post an example of how it has worked in some of CSU's work.
