we're inside it... they take pictures from the inside... if you've seen a picture of ours from the outside, you've seen a computer generated image or a galaxy we expect to look very similar to ours. we can reason quite a bit about what ours looks like but there is no way to be sure. interestingly, even most of the Hubble photos are colorized.

Take photos from Earth (obviously), then generate a 3D image using the photos and the supposed distance to the star or group of stars. Generally photos you see of the Milky Way are either computer generated best guesses or they are of other spiral galaxies which astronomers think look like the Milky Way. Our galaxy is nothing special. There's no shortage of look-alikes out there.

You are right, you would need to go outside our galaxy to take pictures of it. What we do have instead, is a nearby galaxy called the Andromeda Galaxy - or M31. This galaxy is believed to be very similar in both size and shape to the Milky Way - and hence, pictures of it are often used in relation to the Milky Way as well

They don't.
There are no pictures of our own galaxy.
There are, however, computer models based on observations of stars in our galaxy (their positions, sizes, brightnesses etc), and from these simulations of what the galaxy would look like from outside are produced.
Those who say they are taken from satellites relaly need to go back to astronomy 101.

aha! tricky question...anyway i dont think there are any real photographs of our galaxy. They're all probably just computer generated models as someone said earlier. Of course, it's all hypothetical because they have to work on what our galaxy looks like from the inside.

Satellite imaging. What do you think the big cameras that are mounted within the Hubble Telescope are for?

with satellites.
