tkInter and Pillow don't display any images in GUIs - program gives errors instead

[SomeRandomGuy]

Is it even possible to set GUI element on a GUI element? I chose to use Guizero because it doesn't require me to convert all .jpg files to .gif, and the only thing I can do is either placing them on top of the image right in the middle or to the sides of the image. https://imgur.com/a/iqKOfNg

from guizero import *

app = App(title="Gui", height=576, width=864, layout="grid")
pic = Picture(app, image="characterwindow01.jpg", height=576, width=864, grid=[1, 1])
text = Text(app, text="Text text", color="#FFAADD", bg="#000000", grid=[1, 1])
text2 = TextBox(app, text="Text textbox", grid=[1, 1])

app.display()

I'm starting to think I should use another language for my GUIs...
