I have a series of pictures (jpeg or other format), and want to save them and then send them to another person, such that the person can click through them, since the pictures tell a story :-) How is that possible to achieve?
You can do this with any gallery. You can either do it with an online gallery that you can send them a link to or they could simply view it in a gallery program. Windows includes a built in gallery viewer that will let someone walk through the photos in a folder in order for example. You could also make a video out of them, though this would take considerably more space.
Another approach would be to use some program with a publicly available viewer. For example, if you have Powerpoint, you could put them in to a Powerpoint presentation and there is a free Powerpoint Viewer for Windows machines at least. That's not the only option, but there are far too many possible options to enumerate.
