would → asks for permission
could → asks for ability to do something

In the first picture, we can see atwo womaen and a teenage girlin the woods playing with the snow in what look like a park, while the second shows a middle-aged man holding a little girl by the hand alongnear the socean.

It's hard for me to tell whether the person covered with a spray of snow is a teenager.

Please, look up the definition for "middle-aged." I can tell that you haven't looked it up yet.

Also, be careful of seeing too much detail in an image when it isn't there.

Judging by the way they are acting in the first picture, I am fairly sure that they are friends or even part of a family, who knows?

In the same way, the people in the second picture must be part of a family, too.

The biggest difference is that while the people in the first picture are wearing warm thick clothes so the photo must have been taken in winter,the first photo must have been taken during the winter because the people are playing with snow while the people in the second are wearing light clothesone are on a beach so the photo hwas probably been taken in summer or springtaken somewhere where the climate is warm.

EveryonBoth people in the first picture seems to bare clearly overjoyed.

Both people in the first picture are clearly happy.

Both people in the first picture seem overjoyed.
Both people in the first picture seem very happy.

In the first picture, we can see a woman and a teenage girl playing within the snow in what looks like a park, while the second shows a middle-aged man holding a little girl by the hand alongby the sea.

We almost always say "in the snow"

In the same way, the people in the second picture must be family too.

Or "in a similar manner"
