I do not understand why the html export doesn't support gif files
Xara3D6 and Xara Xtreme Pro v4 both offer export in animated gif!
Animated GIF remains very widely used as many applications are capable of creating the files, and it remains the only animated image format capable of being rendered in nearly all modern web browsers without the use of a plug-in.
I know you can always tweek the html code - but why!

I seem to remember talk in this forum about people disableing flash and
popups altogether. So flash isn't all that!
