Button Picture Attribute issues with Tkinter

I'm having weird issues with some iterated buttons that are made inside of a function. I have my button list as a global variable and photos are saved within my main python folder.
When I use the Button image= attribute, the buttons aren't clickable and are kind of greyed out with no picture. When I use the Button text= attribute, the buttons are clickable and the text pops up, but the width and height attributes don't run. I haven't been able to find similar issues/answers here.
from tkinter import *
from tkinter import filedialog as fd
from tkinter.messagebox import showinfo
from PIL import Image, ImageTk
def OnSomeClick():
---Some Code---
if Orientation == 1:
for i in range(len(Ordered_xCoord)):
InitButtonPhoto = '{}.png'.format(i)
ButtonPhoto = PhotoImage(file=InitButtonPhoto)
ImageButtonList.append(Button(action_window, command=Command, bd=3, width=110,
height=85, image=ButtonPhoto))
ImageButtonList[i].grid(row=Ordered_yCoord[i], column=Ordered_xCoord[i])
#this top if statement is what runs with my test; the bottom is my original
else:
for i in range(len(Ordered_xCoord)):
ImageButtonList.append(Button(action_window,
image=PhotoImage(file='{}.png'.format(i)),
command=Command, bd=3, width=85, height=110))
ImageButtonList[i].grid(row=Ordered_yCoord[i], column=Ordered_xCoord[i])
When loading the photo through PhotoImage(Image.open(file)), there is a traceback error. I'm not too sure why my photos are out of scope/garbaged or why the command working is dependent on the photo saving.
Traceback Error with Image.open:
Exception in Tkinter callback

Thank you, Matiiss and BryanOakley! The fix was a combo of the latest comment and putting my changing the formatting of my image list.

--some code---
for i in range(len(Ordered_xCoord)):

Image_List.append(z)
---more code----
if PaperOrientation == 1:

Kind of sloppy on my part, but it works.

Exception KeyError if call focus_get() when down arrow clicked on widget Combo

Try to view where the focus by following code, but get Exception KeyError if call focus_get() when down arrow clicked on widget Combo.

label.configure(text=f'Focus at {root.focus_get()}')

return w

My question is how can I get where the focus, but to avoid situation like this one. Maybe try except statement can skip exception, but it will get wrong focus at that moment.
[Update]
def show_focus():
try:
label.configure(text=f'Focus at {root.focus_get()}')
except:
# root.after(100, show_focus), if this statement put here, this function will stop if no exception
pass
root.after(100, show_focus) # statement here to keep update where the focus

You can get over the error by ignoring each press on the 'popdown' button.
def show_focus():
if str(root.tk.call(combo,'state')) != 'pressed':
label.configure(text=f'Focus at {root.focus_get()}')
else:
label.configure(text=f'Focus at {str(combo)}')
root.after(100, show_focus)
This is a way around the issue as 'popdown' button is not identified by nametowidget()(which is used to return the widget name when using focus_get()). I was able to find a similar bug at https://bugs.python.org/issue18686

Insert an JPG image in Python using Tkinter

i'm trying to insert an image using Tkinter but it doesn't work, there is an error message saying : (In fact it is saying that python can't recognise the data in image file)
Traceback (most recent call last):
File "E:/Tle/ISN/Programs (Pyhton)/IMC (Widget) ULTIMATE.py", line 10, in <module>

_tkinter.TclError: couldn't recognize data in image file "C:/Users/mateo.PCMATEO/Pictures/MonCoachPersonnel.jpg"
And here's the code i've entered :
from tkinter import*
import tkinter as tk
window = tk.Tk()
window.title("My Personnal Fitness Coach")
window.geometry("400x500")
window.configure(background='grey')
canvas = Canvas(window, width = 100, height = 100)
canvas.pack
my_image = PhotoImage(file="C:/Users/mateo.PCMATEO/Pictures/MonCoachPersonnel.jpg")
canvas.create_image(0, 0, anchor = NW, image=my_image)
window.mainloop()
The problem is that i don't have any modules except the ones predownloaded with python and i don't want to install some yet. So could you help me?

if you use jpg you must do so
from PIL import ImageTk
then
my_image = ImageTk.PhotoImage(file="MonCoachPersonnel.jpg")
canvas.create_image(50, 50, image=my_image, anchor=NW)
I've simplify the file dir, note that I've increase the dimension of the pic, from 0,0 to 50,50.

Please, try this (only change image file path)
from tkinter import*
import tkinter as tk
from PIL import ImageTk, Image
window = tk.Tk()
window.title("My Personnal Fitness Coach")
window.geometry("400x500")
window.configure(background='grey')
canvas = Canvas(window, width = 100, height = 100)
canvas.pack()
photo_image = ImageTk.PhotoImage(Image.open('xxxx\\racecar.jpg'))
my_image = canvas.create_image(0, 0, image=photo_image, anchor=NW)
# my_image = PhotoImage(file="xxxx\\racecar.jpg")
# canvas.create_image(0, 0, anchor = NW, image=my_image)
window.mainloop()

What am I doing wrong?

You are trying to create two instances of Tk window. You can't do that. If you want second window or pop-up window you should use Toplevel() widget.
Also, self doesn't mean anything in this context. Using the widget's image property would be better to keep a reference.
import tkinter
ssw = tkinter.Tk()
def six():
toplvl = tkinter.Toplevel() #created Toplevel widger
photo = tkinter.PhotoImage(file = 'American-Crime-Story-1.gif')
lbl = tkinter.Label(toplvl ,image = photo)
lbl.image = photo #keeping a reference in this line
lbl.grid(row=0, column=0)
def base():
la = tkinter.Button(ssw,text = 'yes',command=six)
la.grid(row=0, column=0) #specifying row and column values is much better
base()
ssw.mainloop()

_tkinter.TclError: can't pack when trying to add ttkcalendar into tkinter GUI

I'm trying to add a ttk calendar into my Tkinter GUI. The problem is that it raises _tkinter.TclError: can't pack .34164128 inside .34161248.34161448.34161608

Do you know where is the problem?

The fault is that you don't have an __init__ method in the class CalendarDialog. So just rename the body method to __init__. Now you have initialized the instance every time one is made and a pack() method is defined.

I also encountered this problem putting a ttkCalendar into a Dialog box.
I suspect the author of this post "borrowed" the same code for building a calendar as I did:
https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=2ahUKEwiWgYWKsJ3nAhVKl3IEHYrhCU8QFjABegQICBAB&url=https%3A%2F%2Fsvn.python.org%2Fprojects%2Fpython%2Ftrunk%2FDemo%2Ftkinter%2Fttk%2Fttkcalendar.py&usg=AOvVaw0ifTox4EI7CtBFWlRYD_m9
There are two problems I found using this code to create a Calendar object and placing it into a Dialog box.
The first one causes the traceback as shown in the post. The fix is to modify the ttkcalendar.py file to pack the calendar when it is created, not after it is created using the pack() function.
Here is the diff:
102c102
< self._calendar = ttk.Treeview(show='', selectmode='none', height=7)
---
> self._calendar = ttk.Treeview(self, show='', selectmode='none', height=7)
109c109
< self._calendar.pack(in_=self, expand=1, fill='both', side='bottom')
---
> self._calendar.pack(expand=1, fill='both', side='bottom')
Once you make this change, the calendar will appear in the dialog box. However, your problems are not yet done. Another exception occurs when trying to set the minimum size of the calendar:
