    Specifically, first image of the full disk of Earth from space (Russian Molniya satellite, 1966-05-30), unless you count the first photo from orbit (Explorer VI, 1959-08-14; turned out poor but technically shows the entire sunlit portion). It was superseded quickly by Earthrise (Lunar Orbiter I, 1966-08-23, first pic of Earth from near another astronomical object), and this first geostationary orbit image (ATS-1, 1966-12-11).

    It does not take much to reach space (100 km) so a camera was launched there as early as 1946. See https://en.wikipedia.org/wiki/Timeline_of_first_images_of_Earth_from_space

        It was really hard to get the early spacecraft to not spin uncontrollably, so even short exposures look blurry.

        Yes, a bit of a letdown but it was 7 years before the next 3, and shortly after Vanguard 2, the first SSTV scanner camera in space, which failed to align to its target latitude of 40°N to 50°N so I couldn’t find any images - presumably only incoherent lines of image data were received that could not be assembled into a 2D picture. Getting SSTV to work was so difficult that they used to make weather and recon satellites single-use: wind film into a shielded box and deorbit.

        Yup, disappointing especially considering it cost way more than a simple 1940s rocket+camera that took decent pics of land thousands of kilometers wide
