Old school yearbook pictures: most of us hate them enough in themselves. Now throw in the thought of your old yearbook photo being posted online for all the world to see, and then spreading like wildfire to boot.

Well, that's exactly what happened to actress Megan Fox.

Once a photo of Fox hit the Web, not only did fans from all over the world flock to see it, but then they started spreading it around as they went. The result: the high school memory that is one of the hottest things going on the Web, today at least.

Fox, 23, started acting in 2001, but never gained any major attention until the advent of Transformers, released in 2007.

Since then, Fox has become one of the most popular actresses in the world. And for celebrities, publicity is publicity and, if anything, this photo will only help serve the purpose of introducing more people to Megan Fox and her films.
