Donna, I didn’t realize you were talking about the animated GIF I posted – I thought you were talking about the OP’s image.
Animated GIFs are tricky on Facebook – simply uploading a GIF file as an image doesn’t show the animation. Posting the link to the IMAGE location (not the page location) doesn’t always show the animation in the preview, either – the viewer has to click on the link to see the image in its animated form on Facebook. However, I’ve uploaded the GIF to Giphy. If you paste this link into your Status box, the viewer may still have to click on it to see it play on their news feed, but at least it shows up as a preview with a “Play” button.
