reading picture from a directory every time is how normal code will do, but is that possible that we can save the picture object at the first time we open it then we copy the picture object and save in our code so that we don't need to read from file next time?

CodePudding user response：

You can use the base64 module to encode the image data in base64. You can then pass the encoded data to PhotoImage with the data parameter.

import tkinter as tk
