It is not clear what you are asking.
you set the loader image (splash) in the facebook app dashboard. not in construct.
but that has no effect on loading time
i mean when the facebook instant game loading ,it will load the resource too slow.
i add instant plugin in the construct project, it decide what resouce to load at begining of game .'
how do i decide what resouce to load at the begining of game in order to load fast.
