I was wondering by the animated images floating around on facebook. AFAIK, facebook tries to stay simple and clean, To provide nice user experience. It has been one of the success factor for facebook in the social networking. However GIF animated images were floating around so I decided to dig in to get what feature facebook has launched now.
After searching for around 1hour, I got to know that it was a security hole in facebook image compression technique which somebody bypassed and it then started spreading. Following is the way to publish animated images on facebook posts.
Upload a small animated gif (about 50 KB or less)as your profile photo (Facebook will flatten animated gifs which are to large, but do not detect the smaller ones). It will then be in your profile’s album. Your icon itself will NOT be animated. However, you will see it as animated in your Facebook profile photos folder, and by going to that photo, & clicking on “share”, it will appear on your wall as animated.
However above technique has stopped working now, since facebook worked on that small bug. Thank god, It might have become an failure point for facebook otherwise.
While searching this URL was useful for me.
