App Behaviour ============= Constraint Height ----------------- The **normalHeight** option will apply a maximum height to each photo item and also adjust the width to keep the item aspect ratio. The purpose of **normalHeight** is to apply constraints on photo dimension so they are not too big which help improving aesthetics and app performance. Sorted ITem --------- The **autoSorted** option will sort input items according to their width, so the smaller items will be seen before the bigger items. If you don't like this behaviour simply set the option to false to disable it.
