The flat earth community has pointed out for some time there was only ever one picture of earth (published in 1972 during the Apollo missions), and it was photoshopped.
After much public pressure, NASA released a second picture in May of this year. 2 pictures in 43 years!
However it was pointed out to me today that the photoshopping dept in NASA is somewhat bored and fed up with painting clouds on composite earths.
If you turn the second image (2015 one) upside down, and look at the right hand side, you can clearly see someone has written 'SEX' in the clouds.
