how to store image in database?

[aspirant12345]

i have build a small website in my PC using PHP and mysql.
it is a social networking site. everything was working fine...... but i noticed that whenever i am saving a profile picture, it is being saved in that folder in which all other php files are stored. so, i reached on to a conclusion that if i create too many users and give them a profile picture each then that folder will be too messy....
My problem lies here......
i was thinking that i am storing my images in mysql databases but in reality it is not being saved there...... plz tell me , how would i make these storage efficient in terms of numbers?

I am using xampp on wnidows 7......

when you are going to upload an image or any files, you need to create a program that will automatically generate a unique name for every files that you are going to save, the file name must be unique every time you are going to upload, example: filename_121212 .jpg, filename_234345 345.jpg,
