The average British person is under the influence of alcohol in three-quarters of of his or her tagged Facebook photos, according to a new study.

Researchers asked British people to reveal how many Facebook pictures showed themselves drinking alcohol or were taken after consuming alcohol. They estimate 76% of their photographs had some connection with alcohol.

“We’re all guilty of going out and having a good time, but nowadays the photos inevitably catch up with us online, so we wanted to look at how much these photos dominate our presence on social media sites," says Rebecca Huggler, co-founder of MyMemory, which conducted the study.

Researchers also looked at privacy settings. Only 12% of the 1,781 Facebook users who were polled don't allow anyone to see their photos, while 58% let friends view their pics. A substantial 26% gave access to anyone.

More than half (56%) admit they had "drunk photos" they wouldn't want co-workers to see and 8% say their photos might cause "serious trouble at work."

Ninety-three percent of respondents have untagged photos deemed "too embarrassing."

Huggler notes many of the photographs with alcohol were taken during special occasions or get-togethers with friends or family. She predicts the holiday season will fuel more photo activity that involves alcohol.

What percentage of your Facebook photos would you estimate feature alcohol or drinking? Are you concerned about who may see them?
