When Facebook was founded by Harvard student Mark Zuckerberg in 2004, the site was used only by college students. By January 2011, there were 600 million plus active monthly users, according to the Goldman Sachs Group, who invested $450 million in Facebook. Many users choose to upload a profile photo to add a personal touch and help friends recognize them on Facebook. Even if you don’t have a photo that is quite the size you want on your computer, you can upload the picture and adjust the dimensions on the Facebook site. Warnings
