Wow, this is harder to answer than I thought.

Yes to relatively normal, well-taken photos showing the person in a range of activities/places/moods. They are only showing their personality and interests, after all.

No to:

• only group photos
• no photos of the person at all, just items or abstract pics
• 3-5 of the same front camera, looking-down-at-phone photo
• photos that seem outdated, especially if it's of an older man with one child (classic scammer)
• holding a fish

My yes: I think this is pretty standard

• a decent photo that shows your full face,
• a full body,
• a group photo, and
• a photo that shows some sort of hobby.

My nos:

• all photos are of selfies only
• toilet selfies
• indoor sunglasses selfies
• photo with just one other girl as if like a couple

But mostly, I prefer bios. I would swipe right to a full bio and only one photo, but I will not swipe if you have tons of photo and an empty bio.

my yes:

1. a decent photo (with an appearance that i like haha)
2. personal photos (just of yourself showing your interest in life)
3. comprehensive bios! this can compensate for bad photos haha

my nos:

1. no profile photo (eg just meme photo)
2. only group photos without one of yourself
3. gym photos (this is a very personal dislike)
4. sunglasses selfies/mirror selfies
5. no bio (shows to me that he’s not very 100% in looking for a steady partner - which is what im usually looking for)

honestly, i only swipe right if i feel i can match my lifestyle with his
