[Mne_analysis] Inhibit figure plot

Bruno,
Can you report your MNE-Python version info? For me the following works correctly (no plot windows are opened):

import mne
import matplotlib.pyplot as plt
# do whatever needed to create your epochs, and then:
for ch in epochs.ch_names:
fig = epochs.plot_image(picks=ch, show=False)[0]
fig.savefig(f'epoch_image_{ch}.png')
plt.close(fig)

-- dan
