Edit #2 :
testing to be done : adding this :
https://lemmy.world/pictrs/image/... *.mp4?format=webp&thumbnail=256
… at the end of URL
Test result : it does show as a thumbnail but it is no longer animated.
Edit :
Only way I can make it appear on the feed as a thumbnail is is if I use an external site containing the *.gif image : putting the URL of that image in the URL field of the post.
to view : open this post since it doesn’t show in the feed …
