I dont know who made this statement, but how true it is! I have observed people's photos in their albums, messengers, blogs, orkut etc. And they say so much about that person. Here is an attempt to consolidate all those random thoughts.
Disclaimer : This theory, "Photo analysis" is intended to be complete non-sense. Any deviation from this or resemblance to any person snapped or unsnapped, is purely coincidental and unintentional!
No photo - There are many types of people belonging to this group. Vast majority are outright ugly and have very low self esteem. Some could be the secretive type, who don't open up to people. Very few are mysterious and love playing 'mind games'. Some schools of thinking place lazy people also in this group.
Close up photo - Most of these people are very confident about themselves(people who are looking into the camera). They love to be liked for the "person" they are. A small section(people who are looking away) are people who fear rejection. They would have agreed for a close up snap, even though they are not comfortable and end up looking away from the camera.
Backdrop photo - These people want you to know whats happening in their life. They consider that "person" and "events" are inseparable. People whose pictures are taken inside Colloseum, in front of eiffel towers, or skiing are undoubtedly this type.
Group photo - They don't have individuality and can easily be influenced. They like to be identified as part of a group and not as an individual.
Constantly changing photos - These people are very vibrant and are always "on the move". Some of them are addicted to attention and a compliment is the passport to their heart.
Unrelated photo - These people have the photo of some child, a mountain, a flower or a Hritik Roshan as their profile photo. These are the 'day dreamer' types. Many of them live in an illusionary world and think of themselves or aspire to be to what they have as their photo.
Most of the people belong to more than one group mentioned above. So, how do your photos look like? ;)
