Facebook recently made it so when you click on a picture you see it in a lightbox. The idea is nice but the execution needs some work. If you would like to go back to seeing pictures normally on their own page follow these easy steps.
1) Click on any picture that you want to see.
2) In the address bar of your browser (where you type in the URLs of websites) go to the end of the current address and delete just the “&theater” part.
3) Hit enter and go back to seeing that picture normally.
