<![CDATA[[closed] Images not working]]>I'm trying to load an image but everytime I use the blocky version of this code

from m5stack import *
from m5ui import *

clear_bg(0x222222)



btnA = M5Button(name="ButtonA", text="ButtonA", visibility=False)
btnB = M5Button(name="ButtonB", text="ButtonB", visibility=False)
btnC = M5Button(name="ButtonC", text="ButtonC", visibility=False)
image1 = M5Img(64, 19, "res/miniM5os.jpg", True)


lcd.fill(0x3333ff)
image1.changeImg("res/miniM5os.jpg")
image1.setPosition(0, 0)
while True:
  image1.show()
  wait(1)
  wait(0.001)

I just get a blank black square on the screen.

It would be better however to have an open source solution such as gimp

@ajb2k3 I had seen a tweet on twitter.

JPG format needs some conditions.
・progressive off
・not Matte color

and use MS paint is no problem.

i'm on osx and using G.I.M.P

Yup followed those steps but just get a black odd shaped box.

I have occasionally had weird results from certain files. Have you tried other files beside the one your trying to display?
