CHH Create a rectangle the same size as your Flash movie.

Select the rectangle and open the Website Properties > Placeholder menu.

Click the Browse button next to Replace with Flash. Locate and select your .swf file and click Open (I thinks it open, whatever the operative option is). Click Apply then OK to close the dialog.

I believe the .swf file will start playing when the page is opened.

Actually, I just dragged and dropped a .swf file from the desktop onto the page and it works fine. Have you tried this?
