Update of Javascript 2

Horizontals worked, verticals didnt..  What these changes fix, is the
ability to generate GIFs while setup for print output.  The GIFs will
default to a 640x427 size when the setup is running for paper output.
So, now Pic2Print supports generating prints and GIFs withtout changing
anything in the config panel.  Later I'll add a GIF selector for a
selectable default size.
