I need to add filename prefix to files uploaded by file\_column plugin.  
For  
instance the image file uploaded by the user is by name ‘foobar.jpg’  
I need to prefix this image with a random number(‘23\_foobar.jpg’). I  
need to  
write this prefixed name to database too.  
Is there any way to do this ?
