We all have seen the official release of the image of the black hole.

scientists took the image of a supermassive black hole at the center of M87, which is very supermassive but 55 M light year away.

why they don't take the image of the black hole at some nearby galaxy's black hole. There is obviously Andromeda.

In the first place, the question arises why the don't choose a stellar black hole and why black hole at the center of galaxy despite that galactic center might obstruct the visible light due to more and more matter.

Dosen't near by black hole would have gave a better picture?

Because not all black holes are located in galaxies that face us head-on. It's not that easy to take a picture of a black hole when it's behind lightyears of stars, dust etc. M87 happened to be facing us head-on, which is why we could take a picture of it. I'm not sure how it was for Saggitarius A* but it must have been something similar.
