 internet connection is not that great and jpeg screenshots are faster
 to upload than png screenshots. So what I do is for each file

 extension), and then I use the ~convert~ command from ~imagemagik~ to
 convert it from its original format to a jpg format --- ~imagemagik~
 detects the formats based on the extension.
