This country has verdant steep hills, and a valley, but the most of the greenery seem to be grass and shrubs… Can’t quite figure out if it is to the north or south of Taiwan.
Thailand?
Nein. It’s to the south of Taiwan.
Like… the Cagayan Valley kind of right to the south of Taiwan?
Further south
Is it Papua New Guinea?
Close, very close
Indonesia?
That’s correct. The Indonesian part of Papua

Well, we have played this game for a long time and there are no rules against using any form of tools, because you cannot control the way people find the answers. What you can control, however, is making an image unsearchable by choosing one that is not in the worldwide data base of images. So random screenshots or self-shot images of not well known places work best.
By the way, I would love to just guess without any tools, but not everyone is playing like that so that does definitely NOT work.
