You have to make one page with this code for every picture you want to show and give it a name for example:
"Page_one.html"
And this is the part that goes here to show your next page.
<<>META HTTP-EQUIV= "Refresh"Content="15;URL=http://url of the next page.html"<>>
put your "next" gif or jpg url in this part of the code
<<>link rel="next" href="http://url of the next pic orslide here.gif orjpg"<>>
(this will make your picture to download before you get there)
This META and link part of the code will prepare your page and your picture to be show instantly on the next page. You need to fill this correctly in order to be shown in your next page other wise there will not be a page to be show.
So what your are going to put here like i said before:
its your " (META) next [page.html] "
and your " (link) next [.gif or .jpg] "
So your next picture can be show
Now the picture that you want to show in this page goes in
<<>img src="//url of the pic or slide here" height="325" width="450"<>>
