What computer Language (ex. CSS, HTML, PHP, Java) was used to develop Facebook's Photo-Tagging Features?
I have decent knowledge of Web Programming (HTML, CSS, and learning PHP), but was trying to understand how this feature was developed.

javascript was used to allow the user (you) to select the face and ajax (javascript + php) was used to search the name of the person you just selected then more php was used to submit a query to one of their databases as that person tagged in that specific photo at this location (x,y coordinates)
its a lot of code but pretty straight forward if you know a ton of javascript/ajax |

JavaScript to get the exact coordinates of the tag in the photo: x1, y1, x2, y2
And, I guess HTML's <img> and <area> tags to display them on the browser. PHP to store the cords, name and other details in the database. AJAX to send the data to the PHP. :-) |
