The 10 Most Retweeted Photos of the Week [PICS]

This week's most popular photos re-tweeted in the English language were a mixed bunch, peppered with both tragedy and comedy. Unfortunately, the most re-tweeted picture was of a tragic young victim of brutality, and another one was a picture of a missing person whose story had a much happier ending.

On the other hand, most of the pics were more lighthearted, showing you people and their activities from a completely different perspective. Even though there weren't as many celebrity pics this week as usual, of course, there's a hint of Justin Bieber in there, who seems to dominate all things Twitter.

As you peruse the 10 most popular Twitter photos of the week, compiled for Mashable by real-time photo search engine Skylines between Dec. 2 and Dec. 8, 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 of days ago.
