Depending what level of security you want on the photos, simply name the photos as username.jpg and then when they're logged in you have their username and therefore can put the right image there

 

but what if the username of image is same of any 2 student ?? then ??

 

User name will not be duplicated.

 

Usernames have to be a unique identifier, most also don't allow users to change their usernames but if you did you would need to ensure the filename is also changed at the same time.

You would discard the original filename of the uploaded file as it risks duplication.
