LinkedIn is a business community, not somewhere to showcase your beach-tanned body to friends and family. Your picture needs to represent your professional aspirations and be appropriate for the industry you are in. Here are a few basic rules:

• no party or beach pictures (unless that's your job)

• don't make your photo too small or low in quality so it looks pixelated or grainy

• don't use pictures of yourself within a group

• don't go for poorly lit black and white pictures

• hire a professional photographer; a selfie (especially one done in a mirror showing your hand holding the camera) is a no-go

All that said, whatever the picture is, it is still better than no picture.
