I've just received an email that contains a remotely hosted animated png. The png file is a countdown timer. Here is the URL:-
https://img.kickdyn.com/57/1MfiOGVFjvmaMMHd3VZv/imgancnt.png
Can someone please help me explain how this works? I would have expected that each time I load the file it would start playing fomr the same point, effectively resetting the countdown, but that seems not the be the case.
How does the PNG file know where to resume it's countdown from?
2The file in question includes 30 frames, so after 30 seconds the magic is over -- or the page where this image is embedded needs to reload it. – mpy – 2013-07-10T15:50:44.537
Ah yes! I hadn't considered that it was dynamically generated each time. That must take a bit of a hit on the server. – Rob – 2013-07-10T15:57:31.937
