Jupiter saves an empty photo, although it shows it before. How to fix that?

I'm reading and output the picture as a plot:

import numpy as np
import os
import matplotlib.pyplot as plt
import matplotlib.ticker as tkr


fig, ax = plt.subplots()

path = 'photo.jpg'
im = plt.imread(path)
ax.imshow(im)

Output

After I want to save it and check(see) the image before saving, but my code generate empty image:(

plt.axis("off")
plt.gca().xaxis.set_major_locator(tkr.NullLocator())
plt.gca().yaxis.set_major_locator(tkr.NullLocator())
filename = os.path.basename(path).split(".")[0]
output_path = os.path.join("test", filename+".png").replace("/", "")
plt.savefig(output_path, bbox_inches="tight", pad_inches=0.0)
plt.show()
plt.close()

Output
