** ** So on first slide( if lg.on if false that is first slide) loadContent() should start loading immediately

** ** So set timeout s.speed + 50

** ** It has recursion (rec) parameter. if rec === true loadContent() will call preload() function.
** ** preload will execute only when the previous slide is fully loaded (images iframe)

** loadContent() <====> Preload();
