The 10 Most Popular Photos on Twitter This Week [PICS]

There are millions of photos linked in tweets each week, but we've looked for the ones that resonated the most with Twitter users. We've narrowed them down for you, sifting through 26 million tweets, and found the 10 most popular photos on Twitter, posted between Dec. 16 and 22.

How on earth did we choose these? First of all, we left out spam advertisements for events, and we've also eliminated photos from non-English-speaking countries. The pics were all compiled for Mashablevby real-time photo search engine Skylines. Keep in mind that if you click through to the pics' originating pages, the number counts might be different because Skyline made its determination a couple days ago.

This week, Justin Bieber heads up the top of the list as is his wont, filling the top two slots and appearing twice more. Further down the celebrity-spangled list, you'll see Taylor Swift again, occupying the same position she did last week. Keep clicking through our gallery, and you'll even see a couple of surprises.

Peruse and enjoy the 10 most popular photos on Twitter this week:

This photo of a girl, presumably with cancer, drawing hair on her head in the mirror, was last week's number 4. It was also in a top 10 from last month. At the time it was tweeted by @HeyItsRemi, a California woman with a little more than 9,300 followers when she posted the image to Twitter, along with the tweet: "if you look at this picture and not retweet you are heartless." There wasn't any text in the image itself. Two weeks ago, the picture, which was edited with the text that is shown on this picture, was tweeted by @castronovology (200+ followers), who tweeted it along with 'How many RT's can this little girl get? ?'. This week, the same image was posted along with the same tweet by @Jake_Rosenbauer (500+ followers).
