you take a picture of a letter you have written to someone or someone has written to you. you could also put a picture of your favorite letter; like mine would be 'j'.
I see your facebook picture
It means your main profile picture
There is no 'P' in "facebook."
It just means that they really like that picture and they want to 'own' it.
you would tag people in a picture, say if theres you and a friend in a picture and you can select their face in the picture and tag them with their name.
On Facebook, the abbreviations of UMP usually stands for ugly mental picture. This term can be used when joking with a friend.
that means they dont have one lol
Challenge. Perchance.
Nothing. You are over thinking it. Something just caught this attention.
Being tagged means someone uploaded a picture and identified you as one of the people in it.
it means it waiting to start uploading.
I think you mean for you DSi if you do go to the camera app and touch album, select the picture you want and click the little button that has the facebook symbol.
