The data for this image has not yet made it to ESA's Planetary Science Archive, which is a pity. I don't know if there were any others taken by Philae during the encounter. Rosetta took plenty of its own amazing photos during the encounter, catching not only Mars but also Phobos and even Jupiter; I had a lot of fun playing with those.

There's something magical about seeing pictures of hardware on other planets. I have a special keyword for pictures like that in our image library.
