Depends what आप are talking about...if आप mean comments, then well, आप just go to the दीवार and there will be a blank अंतरिक्ष that says "Write something on the ____ wall." It's pretty straightforward...but if आप need help still then टिप्पणी दे on my post, add me as a friend, and message me...
JUST LOOK AT THE THING आप WANT TO ADD AND PRESS ADD A ______!! how do the कैप्स feel on you, huh? आप have annoyed me so i will sic my dog on you. WHISTLE GO!
Click answer question. When it shows the white box, click 'add an image' which is under the box. Then, as I do, pick a picture, drag it to the desktop and then just drag it toward Choose File and then it'll load and then just enter the text and click 'submit new response'.
Now please learn to ask सवालों in a orderly manner.
