Depends on what your architecture is like, but QList<QImage> would not likely be something that you should use.
QList<QByteArray>: requires minimum in-memory data, requires cascades to decode the data every time you show it in an ImagView
QList<bb::cascades::Image>: requires more memory to store decoded image, showing it in an ImageView is the quickest possible.
QList<QUrl>: requires the least amount of memory, but images must be stored on disk. Allows you to use the cascades built-in image caching.
