The black border thing, I don't know the reasons very well.
Because I always obtained very good results in conversions, but hey, if I saw these days that all the gifs that I search on Google for laughter with friends, either do not move, or go crazy. (I would recommend you convert it again, and check it before with any video viewer, I check them with VLC.)
On the other hand, once you have the converted and revised gif on your pc, just like the IMG you must host it in a hosting that also supports GIFS (many do not support .gif, .swf, .webp files)
* If you save it in your Google drive, it will support the .webp format, which seems to be giving very good results, and you would only have to use the uther 'scale' parameters.Now it only remains to discover (being a basic member, I cannot do that task) if you should use the flash or browser script.
