looking for scripts that do simple image display

[Skaperen]

i would like to have a minimal script to display an image. very minimal would support just one image file format although supporting two formats would be nice. it needs to start at the command line. it can either open a new window for the image or put the image in the root window. an option to do either would be nice. a timer to take down the image in a specified time would be very nice. support for a key input like Q or ESC or just any key or mouse click to have exit would be nice. Tkinter or PyQT support would be great but any would be fine. this is for learning by example so fancy elaborate image applications would be of much less help. i hope it unpacks the image file into raw pixels and displays those. Python3, only (does this need to be said these days ... i was debugging an issue with a script from Ubuntu just this afternoon that still uses 2.7 so i wonder).
