Wow. Amazing. Like what kind of an answer is “if you’re inside a car you can see the car”. This doesn’t answer a damned thing!
We don’t “know” what kind of galaxy we are in because we’ve never seen it from the outside. That would be impossible with our current technology.
Instead we have made very smart evidence-based assumptions as to how our galaxy looks.
What we know is that we are definitely in a galaxy because the general structure of the universe precludes such a conclusion. The extreme vast majority of matter is condensed in structures that are very uniform, we call them galaxies, therefore we must also be in one.
On a very clear night in certain parts of the world we are able to see in the sky a large elongated collection of stars which the ancients called the Milky Way because it resembles milk flowing down a smooth surface or something along those lines. What we currently believe is that that elongated formation of stars is an arm of one of the spirals that comprises our galaxy. We are also able to look at other structures using telescopes in our galaxy for example we have determined that we have a supermassive black hole in the center as many other spiral galaxies do as well.
So to answer your question we cannot see the Milky Way galaxy as a whole only certain parts of it and we’ve been able to draw conclusions by seeing other galaxies.
All the other comments here making neurotic epitaphs and idiotic analogies about how seeing something from the inside is the same as seeing something from the outside is just dumb and pompous if you don’t know the answer don’t say anything.
We do know quite well what our galaxy looks like thanks to great advances in astronomy. To use your car analogy, it would be like using “X-ray”technology to map the exterior from the interior and get a reasonably accurate picture of the shape of our car.

Wait we can know what it looks like though. They can plot the distance and position of the stars and then they will have a model of its shape as a point cloud.
The original question is very vague and in general difficult to answer without asking additional questions to clarify so I answered the question in the spirit not in the letter.
We’re on the Earth — how do we see the Earth? By seeing other parts of the Earth that aren’t ourselves. The same is somewhat true for the Milky Way. And like on Earth, you can’t see the whole thing without leaving it, because we only get to see the stuff that isn’t blocked by other things.
In case you mean pictures like this; http://upload.wikimedia.org/wikipedia/commons/8/82/Milky_Way_Galaxy.jpg - they are not actually images of the Milky Way. As you’ve guessed, we can’t directly see it in its full spirally goodness from the inside. Instead, these pictures are either artist’s impressions based on scientific understanding, or pictures of different galaxies that are reckoned to be pretty similar to the Milky Way.
Though someday we may find a gigantic space mirror that allows us to see our own galaxy by zooming in on it enough.
The space mirror will be formed by some weird gravitational pattern that happens to send light back the way it came. Not like literal glass floating in space. Just some kind of optical distortion that acts as a mirror.
But we’ll be looking at our galaxy a long time ago.
Over 26000 years ago if the mirror was placed at the very edge of the milky way. I wonder how many light years away the mirror would have to be to fit the whole image of the galaxy inside it.
I just can’t even begin to get my head around those numbers, I am a tiny insignificant ant.
It would more be a matter of the diameter of the mirror. It could be one inch outside the galaxy and give us a view of the galaxy.
Because we are inside it. You can literally just look up at the sky and there it is! It does help that we are more toward the edge of it, than towards the center.
As for like a zoomed out image of the entire thing? Math as well as microwave and other radiation maps taken with powerful telescopes and instruments either on Earth or in orbit. Most of the images of space you might see are doctored in a way to make them look better to human eyes; they were actually constructed from data that wasn’t necessarily visual. All the different colors of a rainbow nebula, for example, mean something, and the nebulas do not actually look that cool when seen with the naked eye.
To add to that about the nebulas, they don’t look like they do I’m scifi either. Gas clouds or plasma clouds visible to the human eye. If you piloted a ship through most nebula it would look no different than the rest of space around you. Space is BIG yall
The same way as I can see most of my body even though I am inside it. Indeed, without a mirror I cannot check whether I got a drunk tramp stamp tattoo last night, but I can still see most of my body and get a decent idea on the shape it as, especially when comparing with other’s people bodies
These analogy answers are weird and not helpful.
OP, they look through telescopes and figure out how far away the stars are. They record it in a little diagram on a computer and eventually they get a good idea of what it looks like from the outside.
We do see it, just not all of it since the milky way is in the way.
The same way I see the hood of my car while sitting inside of it.
Epic Spaceman made a video about it where he showed how it looks from an outside perspective and our point of view while explaining a bunch of other things.
Imagine being on the surface of Saturn. You’d see the rings. I mean, you’d be dead, but you get my point I hope. If not, picture Saturn being the size of rock, but the rings were still there. You’d still see them, yet you’d be “in” Saturn.
Your question needs rewording because as its written right now the answer would be that you just look up at night and all the stars you see, are the milky way.
Same way you can see your living room
Picture you’re standing in a giant swimming pool. You can see the pool surrounding you.
Anyway it seems like that would be one of the best places to see the Milky Way.
It’s very big, we’re on the edge
Can you see the tip of your nose?
