title: Lazy Loading of several images in UITableView
body: <p>What are the best practices to download several images and load each of them in a UIImageView which is inside a UITableViewCell? Particularly, should I resize/replace the UIImageview after downloading or should I resize the image to fit into the UIImageView. Note that resizing/replacing UIImageView also resize/replace UITableViewCell. Will it cause any issue? </p>
