How can I add images to annotations in Matplotlib?

You can use the AnnotationBbox class from the matplotlib.offsetbox module to add images to your annotations.

Can you show me a code example for that?

Sure! Here's a simple example:

import matplotlib.pyplot as plt
from matplotlib.offsetbox import AnnotationBbox, OffsetImage

fig, ax = plt.subplots()
ax.plot([0, 1], [0, 1])

image = OffsetImage(plt.imread('path_to_image.png'), zoom=0.1)
annotation = AnnotationBbox(image, (0.5, 0.5), frameon=False)
ax.add_artist(annotation)
plt.show()

What if I want to change the size of the image?

You can adjust the zoom parameter in the OffsetImage function to change the size of the image.
