title: Is there a way to change a gif into a jpg but still maintain animation properties?
body: <p>I've found in a couple of places where normally only jpgs would be accepted, that users have uploaded gifs instead. What I think is going on, is that they're changing some of the code in the gifs to proxy a jpg and thus bypass systems which usually only take a jpg file. Is there a specific way to change a gif's header information to somehow imitate a jpgs?</p>
  
  <p>I'm experimenting to see the logic behind this. I've noticed that among all the code found in gif files, they usually begin with a 'GIF89aoo'string. Anybody familiar with this?</p>
