A new Facebook survey found that 26 percent of people crop vacation photos to hide body parts they feel look unattractive.

This isn't too suprising, given that many users use social media as a way to show off their lives, even if they are exaggerated portrayals. And who wants to look unflattering in a photo?

According to the new survey, nine out of 10 Americans share their vacation photos on Facebook. 54 percent of them "capture holiday moments," whereas 61 percent do so to "update family/loves ones on whereabouts." 64 percent do so out of the simple "enjoyment of sending photography."

The data from research firm YouGov, commissioned by CyberLink Corp., suggests that Facebook friends don't like their News Feeds to be bombarded by other people's vacation photos. While they might be jealous of the perceived lives others portray, 34 percent of Americans would actually consider unfollowing or blocking friends that post too many holiday photos.

"Our social news feeds are dominated by 'gloating' photos of friends and colleagues on holiday, and while capturing photos and sharing them on social media has become an integral part of the vacation experience-- there is a way of doing so without annoying friends and family," says Alice H. Chang, CEO of CyberLink. 

The survey found that Facebook is the top social platform where people share their vacation photos, more than three times than that of Instagram, and more than four times than that of Twitter.

25 percent of American Facebook users crop their vacation photos so they are the main focus, and 68 percent retake the photo at least once if they don't like the way it come out.

Most American Facebook users post their vacation photos in 60 minutes or less upon returning home. The types of photos Facebook users share while on vacation include: hotel rooms (29%), meals (27%), a cocktail (17%), self in sunglasses (19%) and the surrounding landscape like the pool, beach, mountains, etc. (72%).
