How can you tell the difference if a picture is of a sunrise or sunset
just by looking at it ? ? ?

Color, or timestamp (if the time correct)

Good question, here are two similar images. One is a sunset, the other sunrise.

We can look for a variety of clues but even with those it is easy to mistake one for the other.

Usually it's the color. Sunrise colors are cooler and paler, but I also saw many really pale sunsets.
According to the astrophysicist Neil Degrasse Tyson, director of the Hayden Planetarium in New York generally, when at least a part of the sun is visible, you can tell by the angle - because of Earth's tilt, the sun doesn't rise or set along a vertical line, but at an angle. When viewed from all latitudes north of the Tropic of Cancer , the sun always rises at an angle up and to the right, and sets and an angle down and to the right.

What Elnina said. Any questions?

In-case anyone is curious, the fist image with pine trees is the sunrise, the other is a sunset. Bother were taken in the same week in October in Northern Maine.

Here are a couple of good articles that get into the detail of why we see sunset/sunrise colors and why some are much bigger than others.
