STRANGER THINGS UPSIDE DOWN ANIMATOR
This file will turn any photo into a popular, dark “Upside Down” world from your favorite TV show. Animated .GIF is great for posting on social media, for emails and websites. Size of the file is 800×450 which is perfect for sharing and usage, since the filesize is still on the low side, and the file will load faster.
I suggest you upload your .GIF to Giphy (or some other 3rd party gif hosting servers) and then just use the link to serve your animation really fast, even auto-playing it on facebook
