what you do is run is in max (or what ever 3d program you use) Render your animation in Image's then Open them in adobe flash (or what ever flash program you use) then export to flash/swf, to Creat the Preview do the say but set the res to 150 x 150. Depending on how long the animation it should be 1 MB to about 7 Mb +.
As you manage to create a swf file?
My problem is that the gif files are too heavy.
as a 3d artist myself , I have to say this is a very good mesh .
well done,
