Well they are both you. That is obvious. But if you are using the pic for professional purposes, use #2. If you are using it for casual, use #1... Both are nice, but would be much better with smiles.
Wat u posting ur pic for some marriage related sites ? If soez go with the recent one and not from ages ago.
you know what your post makes me really happy today i almost forgot that i am sleepy and tired to tell you honestly if your going to use a picture for your profile then use picture number 2 looks formal and decent.
