yes this is default behavior of PHP file uplaod script, if file is already existed there then it will overwrite your old file.
For avoid this, you need to append some unique string in your file name like "time()" so if your image name is like "abc.jpg" then it will converted in "abc1292872879.jpg" so next time if same image will upload ten it will be unique with time() variable.
Best luck..
