Note: this for educational purpose
hey guys coming up with my new post. Hope you all are doing well.
This post is on Facebook.
Few week back I discovered a way to see current privacy protect profile pic. The method works on
anyone's profile pic who don't want to show there profile picture in public mode. I complained to Facebook.
But Facebook official replied that this is none of any privacy concern to Facebook user ,below is the reply i received:

No matter what i call it a Facebook tweak.

So i decided to share this Facebook trick with all my blog visitors. Once again thanks for you big support and your valuable comments and regular visits because of which' Bloggerpooint ' is improving it's ranking.Do like bloggerpooint on Facebook page.

Here is the Facebook hack:
Every Facebook user knows that we cannot view the complete(full view) profile pic of a Facebook user until they are set to public. For example you visits a Facebook user profile who has set his/her pic to privacy view 'Only me ' or 'friends of friends' and you click on the profile or display picture ,no matter how many times you click on the current profile pic it will not open. the size will be 160x160.
But now you can-

This can be done using any browser and os.
I did it using Google chrome on windows 8 professional operating system
Steps:
1) open the victim profile
2)right click on profile pic and select "Copy image URL".
3)open a new tab in browser and paste the Copied link.
4) example: https://fbcdn-profile-a.akamaihd.net/hprofile-ak-frc3/t1.0-1/c62.0.160.160/p160x160/10153016_1397328040549004_1084561891810575775_n.jpg

5) Just by editing and modifying the link little bit we can see the full view of the profile pic.
Example:
ORIGINAL LINK :https://fbcdn-profile-a.akamaihd.net/hprofile-ak-frc3/t1.0-1/c62.0.160.160/p160x160/10153016_1397328040549004_1084561891810575775_n.jpg

MODIFIED LINK: https://fbcdn-profile-a.akamaihd.net/hprofile-ak-frc3/s720x720/10153016_1397328040549004_1084561891810575775_n.jpg


Note: I deleted the " //t1.0-1/c62.0.160.160" from the original link and made a change "/p160x160" to "/s720x720".

press enter after making changes in the original link.
Now the profile pic open in full mode.
Now the picture is enlarged.
