        let myImages=["cat.jpg","cat.jpg","cat.jpg","cat.jpg","cat.jpg","cat.jpg","cat.jpg","cat.jpg","cat.jpg","cat.jpg","cat.jpg","cat.jpg","cat.jpg","cat.jpg","cat.jpg","cat.jpg","cat.jpg"]

        let imageWidth:CGFloat = 275

        let imageHeight:CGFloat = 147

        var yPosition:CGFloat = 0

        var scrollViewContentSize:CGFloat=0;

        for index in 0 ..< myImages.count

        {

            let myImage:UIImage = UIImage(named: myImages[index])!

            let myImageView:UIImageView = UIImageView()

            myImageView.image = myImage

            myImageView.contentMode = UIViewContentMode.scaleAspectFit

            myImageView.frame.size.width = imageWidth

            myImageView.frame.size.height = imageHeight

            myImageView.center = self.view.center

            myImageView.frame.origin.y = yPosition

            myScrollView.addSubview(myImageView)

            let spacer:CGFloat = 20

            yPosition+=imageHeight + spacer

            scrollViewContentSize+=imageHeight + spacer

            myScrollView.contentSize = CGSize(width: imageWidth, height: scrollViewContentSize)

        }
