Um amigo postou uma imagem que estava animando diretamente no feed de mensagens na minha página inicial do Facebook. Como isso é possível? Como isso pode ser feito?
Este é o URL usado pelo Facebook: http://photos-c.ak.fbcdn.net/hphotos-ak-snc3/29301_442976909814_310716489814_5773694_3162803_s.jpg

É uma imagem GIF apenas renomeada .jpg
? Provavelmente não.
Não sei se ajuda ou algo assim, mas aqui está a parte (script) que contém o URL dessa imagem:
