I want an app for viewing a group of images in vertical or a pdf viewer without lines between pages.

The images i want to view are divided in parts(need all parts to get a complete image),so i would like to be able to view several images from top to bottom by sliding.I tried to combine the images into pdf but after each page there is a line which doesn't make it feel like a complete image.So i want either an image viewer that lets me do that or a pdf viewer with nothing between pages.

You'd have to use a photo editor to combine them - add each one as a new layer, and position it where you want it. Then save it as a single flattened (no layers) picture. There's no "viewer" that can view multiple images as a single image.
