You've bought into a phony argument. Photo's from space are ALWAYS computer generated. They have to be. In fact any photo you take with a digital camera of a phone is computer generated. They have to be. From "How Stuff Works":
The digital camera is one of the most remarkable instances of this shift because it is so truly different from its predecessor. Conventional cameras depend entirely on chemical and mechanical processes -- you don't even need electricity to operate them. On the other hand, all digital cameras have a built-in computer, and all of them record images electronically.
So ALL digital cameras are computer generated images. The only alternative is traditional photography which on a satellite is impractical if not impossible. Take a picture on film and bring them all down to earth?
Maybe you're talking about composite photos taken by satellites near earth? Pictures taken by satellites NEAR earth will NEVER show all of earth. If the earth were the size of an orange then a typical satellite is about a 1/4 inch away. There's no way to get the whole earth in a shot. So those types of satellites take as much as they can as they orbit and then the images are stitched together to make a whole.
However there are several satellites that are far from earth. A NASA satellite devoted studying the climate is a million mile orbit. That's far enough away to get whole earth pics (see this link for the story).
Here's an image:
So essentially ALL photos from space ARE always going to be digitally altered or enhanced in some way because they DATA for the picture is going to be transmitted to earth and then it has to be reconstructed by a color to get correct colors in etc etc etc.
So that argument is all wet and has been since the 1960's when pictures of the whole earth were taken by the Apollo missions.
Here's a nice photo of the clearly spherical Earth taken during Apollo 8:

I don’t expect to make any headway with people who worship at the altar of NASA et.al. NASA as a part of the Defense Dept. has its reasons for the deceptions, maybe even some good reasons. If you really believe we have a satellite out there a million miles to study climate change on earth, when low orbit satellites are already doing this job quite effectively, who is getting conned? Artist creations using computer graphics making stuff up is what we are talking about, not digital photography of an actual object. Go through the NASA galleries sometime and look at the inconsistencies. China’s shot of the earth from the moon was quickly shown as a photoshop hoax. Nothing has left the earth’s lower orbit for a reason.
