As a woman, I understand that every man is different and unique, so the answer to this question may differ depending on personal preferences, character and experience. However, I will try to give a general idea of what men think when they look at photos of women.

visual impressions
The first thing that comes to mind for many men when they look at a photo of a woman is her appearance. You look at her figure, face, hair, clothes and makeup. These visual impressions can evoke a variety of emotions, from admiration and surprise to dissatisfaction and disappointment.

Wish
Many men admit that when they look at photos of women, desire arises. They may reminisce about their previous relationships, think about their current relationship, or simply fantasize about what it would be like to meet this woman in person.

expectations
Some men may begin to build expectations and assumptions about the woman they see in the photo. They can think of her personality, interests, character, and values. These assumptions may or may not be fair, but they can help a man decide whether he should try to get to know this woman.

Comparison
Many men can compare the woman in the photo to other women they have met before. They can compare her appearance, personality, lifestyle, etc. This can help them understand what they are looking for in a woman and what they like or dislike in a certain type of woman.
