+'''IMAGE VIEWER
+
+PySimpleGUI reads images in PNG, GIF, PPM/PGM format.
+JPEGs cannot be shown because tkinter does not naively support these formats.
+JPEGs can be converted to PNG format using the Python Imaging Library (PIL)
+package prior to viewing them using PySimpleGUI package.
+
+Sample code for conversion from JPEG/JPG to PNGs is hsown in the commented code block below.
+
+extension = values["image_file"].lower().split(".")[-1]
+if extension in ["jpg", "jpeg"]:  # JPG file
