Given
Light travels at 186,000 mps
186k x 60 sec x 60 min x 24 h = 16,070,400,000 miles per day
or 5,865,696,000,000 miles per year.
You would likely need to travel 25,000ly above the galactic plane to see the entire galaxy.
5,865,696,000,000 x 25,000 = 146,642,400,000,000,000 miles to travel.
Our current fastest probe is traveling at appx 56k mph = 490,560,000 miles per year. A that rate it would take 298,928,571 years to reach 25000 ly above the galactic plane then another 25000 (+48,000) ly for the image to reach us at which time we will have circled the entire galaxy once (+18% for the 48,000 ly distance traveled after completing 1 galactic orbit.
We would actually complete 1 galactic orbit 48000 years before the probe arrived at its vantage point.
So your answer is: It would take almost 300 million years to receive a decent image given the state of our current technology.
Even if we could get instantly there, the image would still take 25000 years to reach us
