我按照下面的代码创建了GUI。通过单击图像按钮将显示的图像更改为新图像是否可行，以便在表单更新时保存新图像？此外，在上传更新(和保存)表单后，只显示已填充的字段是否可行？提前感谢

这里有一个简单的脚本，仅用于演示，只有一个Image元素可以保存并加载到GUI中。

import json
from pathlib import Path
import PySimpleGUI as sg

settings_file = 'settings.json'
settings = {'-Image-':None}

if Path(settings_file).is_file():
    with open(settings_file, 'rt') as f:
        settings = json.load(f)

layout = [
    [sg.FileBrowse(target='Browse', enable_events=True, key='Browse')],
    [sg.Image(filename=settings['-Image-'], visible=(settings['-Image-'] is not None), key='-Image-')],
]
window = sg.Window('Window Title', layout)

while True:
    event, values = window.read()

    if event == sg.WIN_CLOSED:
        break
    elif event == 'Browse':
        filename = values['Browse']
        window['-Image-'].update(filename=filename, visible=True)
        window.refresh()
        window.move_to_center()
        settings['-Image-'] = filename

with open(settings_file, 'wt') as f:
    json.dump(settings, f)

window.close()
