[PyGame] pygame image loading error

[BlueClaw]

This pygame code does not work. All I am trying to do is load images to test an animation.

import pygame
pygame.init()

win = pygame.display.set_mode((500, 500))
pygame.display.set_caption("pesto anchovy")
plright = [pygame.image.load('Player/pl_idle.png'), pygame.image.load('Player/pl_move.png')]

char = pygame.image.load('pl_idle.png')
run = True

while run :
    pygame.time.delay(100)
    win.blit(plright[1], (50, 50))

    pygame.display.update()
    pygame.time.delay(100)

    win.blit(plright[0], (50, 50))

    pygame.display.update()

please help.
