sketchfab
I installed CacheViewer to see how to flip the texture,
when uploading a zip to sketchfab
( there is a bug with )
and vcard succeeded.
I had just to flip the texture vertically, nothing to change in the vrml
(so now : cho2013vcard.zip)
here online :

other test OK too : ( texture flipped verticaly , and mesh uncompressed too )
