-Simple Image Browser based on PySimpleGUI
---------------------------------------------
-There are some improvements compared to the PNG browser of the repository:
-1. Paging is cyclic, i.e. automatically wraps around if file index is outside
-2. Supports all file types that are valid PIL images
-3. Limits the maximum form size to the physical screen
-4. When selecting an image from the listbox, subsequent paging uses its index
-5. Paging performance improved significantly because of using PIL
