A little bit of a damp squib … mostly black images or bits of the space craft … this was the best image shown …
They did say that after that was downloaded, they were switching to a different ground station and were still waiting for that to connect. They'll post better images on their blog when they get them.

Somewhat counterintuitively, using the lunar-Earth flyby to slow Juice down at this point in its journey is actually more efficient than using the flyby to speed it up. …. During the flyby, Earth will bend Juice's trajectory through space, "braking" it and redirecting it on course for a flyby of Venus in August 2025. From that moment on, the energy boosts will begin, with Juice being whizzed up by Venus and then twice by Earth—the space exploration equivalent of drinking three back-to-back espressos. …
Multiple flybys save a LOT of propellent
