A little perplexed

I made an animated gif Christmas card for my sister's business and I am a little perplexed.  It posts nicely on this blog, changing colors as it should.  I have resized it to a very small file for the web in hopes that she could post it on her company's Facebook page, Long Branch Trading as a Christmas card for her customers, but it doesn't look like Facebook will show a gif as animated.  She has a lovely gift store and lunch room and I highly recommend that anyone passing through Irma, Alberta make the stop for lunch.
