.GIF in preview

[covoxer]

Thanks! I do have animation now, but should I only see the rectangle and not the actual gif while working on my project?

You can use any object as a placeholder in WD. The rectangle is a usual choice because it clearly shows the area given for the placeholder. But you can use a bitmap if you which. This can make your design easier to work with.
One more note. If you embed SWF via placeholder option, the actual placeholder object is exported and is displayed instead of the flash in case when broeser has no flash player installed.
