tkinter image change within a label when i gpio state changes

Question

i am trying to use an image inside a label to show a change in the gpio state, i have been able to use text to change but now would like to use a picture of and led and a fish image. but i cant get it to find the image.

i get the following errors i am running this in thorney while i delevelop the script

>>> %Run 'use of images for leds.py'

any help would be appreciated

Does this answer your question? [why-edoes-tkinter-image-not-show-up-if-created-in-a-function](https://stackoverflow.com/questions/16424091) — stovfl, May 10 '20 at 17:39
i think its to do with the way i am trying to call up either one or the other in the following part of the script ----------------- root.update_gpio() def update_gpio(root): dhsen =('fish.gif' if GPIO.input(5) else 'oraled') root.dishisensorlabel.configure(image=dhsen) — johnnyh20, May 10 '20 at 20:12
You can't just assign the image filename to `image` option of `Label`. You need to load the image to an instance of `PhotoImage` and assign this instance to `image` option instead. — acw1668, May 11 '20 at 02:58
