In my mysql database I have the file name of the profile pictures.
 
like
ID File_Name
1 1.jpg
2 2.jpg
3 3.jpg
 
and in a folder I am storing the pictures.
Through code I have change the picture in the folder and with the same name as it was. So no change in my table.
 
But browser display the previous picture only until I have clear the Browser History.
 
Help by something which can recover me from my problem.
Either by clearing history through code or any other suggestion.
 
Please help.

That's easy to do by adding a dummy random parameter to the image URL like this:
<img src="./images/1.jpg?dummy=1244356234"/>
 
Instead of using a random number you could just use an increasing counter that gets incremented every time you change the images.
 
Another approach would be to set a header that will prohibit the image being cached by the browser.
