You need to ensure that there's a reference somewhere to every image that you're displaying, whether it's on a button or some other widget, because tkinter itself doesn't keep a reference to the image. Sometimes the most convenient way is to put them in a list, but just pick what makes the most sense for your use case. -- https://mail.python.org/mailman/listinfo/python-list

Greetings, i have this snippet:

All buttons are appearing but only the last button is displaying the image,
any idea?
You need to keep a reference to the image that you passed when creating
the button; tkinter itself doesn't keep a reference to it:
import json
import os
from tkinter import *
from tkinter.ttk import *
root = Tk()
jload = json.load
buttons = list()
images = []
programs = os.listdir('programs')
for i, program in enumerate(programs):
jsonpath = 'programs/{}/cmdlaunch.json'.format(program)
info = jload(open(jsonpath))
photo = PhotoImage(file = 'icons/'+info['icon'])
photoimage = photo.subsample(3, 3)
buttons.append(Button(root, text = 'Click Me !', image = photoimage,
compound = LEFT))
buttons[-1].pack()
images.append(photoimage)
root.mainloop()
In your code, 'photoimage' still refers to the last image, but there are
no references to the previous images, so they're discarded.
(Why is tkinter like that? Who knows! :-))
