what app will used for image sliding automaticaly

[Rukbat]

If you mean a slide show, one image after the other, with a time delay between them, go to the Play Store and type slide show into the search box. If I listed all of them, they'd cancel my account here - long posts are allowed, posts that long aren't. (There are about 250 apps relating to slide shows on the first page alone.)
