* @desc slide function for lightgallery

** ** On first slide we do not want any animation like slide of fade
** ** So on first slide( if lg.on if false that is first slide) loadContent() should start loading immediately
** ** Else loadContent() should wait for the transition to complete.
** ** So set timeout s.speed + 50
<=> ** loadContent() will load slide content in to the particular slide
** ** 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)
** ** avoid simultaneous image load
<=> ** Preload() will check for s.preload value and call loadContent() again accoring to preload value
** loadContent() <====> Preload();
