I don't see anything in https://github.com/adafruit/Adafruit_CircuitPython_Slideshow/blob/master/adafruit_slideshow.py about image size. They'd probably get pinned to (0,0) or maybe centered, haven't dug that deep. They must be .bmp. Does the REPL list your files (the print_directory() function)? Maybe try it with one or two standard images from Adafruit demos first.

Yeah. It does. They are .bmp and it does list the files. I'll try that.
