The notifications spec has details of the data format for images being sent:
https://specifications.freedesktop.org/notification-spec/notification-spec-latest.html#icons-and-images

It should be possible to reconstruct an image from that, using something like the Pillow library in Python, and then save it to any format you choose.

Best wishes,
