Greasy Fork

I wanted add a gif screenshot to my comment in:
Feedback on Greasyfork - Add notes to the script
When i add it by the add button of the forum, it appear as a jpg ( no animation), but it's a gif because i see with an addon for that on hover it.
I think if i click on it, the gif work (not tested)
If i add it from imgur, the gif work.

Mmmf...
I don't see too many "crazy" shots in the forum.
Principally they are useful.
Let us the choice ?
