Answer 1

Depends on how you obtain the images.

If you get them as URLs, you need to download the actual images. There are examples of doing this.

If you get them as NSData (from downloading them or such), you just have to init a UIImage with the data, e.g. [UIImage imageWithData:] or [[UIImage alloc] initWithData:].

Then you just do what everyone else does when adding an image to a scroll view. There are hundreds of examples. In short, add the image to a UIImageView then add that view to the scroll view using addSubview:.
