Photo download
 

How come that when you're downloading photos on good old dial up sometimes the picture appears gradually as the green bar fills, on other pics you get a blank screen until the pic loads then it displays it all at once. These aren't mucky pictures you understand, honest.

They're progressive jpegs.
