There is no stock way, unfortunately. The Gallery app used to show the location on a small map a few OS versions ago, but now the details of an image will only show the location info, not the map preview. If you open them using Google Photos, however, you can see the preview location on a thumbnail map or open said location directly into Google Maps. Note that this only works per image; if you are looking for a way to see all your photos on a map at once (a-la the now-defunct Instagram feature), you might need a 3rd party app for that (and I, unfortunately, do not know of one that does it).
