javascript - Reveal.js canvas not showing -

i utilize ajax read file names of photographs in directory array. run loop , add together section each photograph follows:

$("div.slides").append("<section class='future'><img src='"+filepath+"'></img></section>");

i enable navigate.right button (as disappears, well):

$(".navigate.right").addclass("enabled");

even though utilize autoslide:5000, cannot see autoslideplayer canvas. doing wrong?

i have started using reveal.js , still getting head around it.
