[eluser]Unknown[/eluser]
I found a problem, when I want to make sure that there
is only one user having one picture file.
With the uniqueness of username, everything is ok ($config['file_name']).
But there is a problem, when an user try to re-upload
different extension of image, (s)he'll have two image file in my server...
I've done with $config['overwrite'] and also $config['file_name']...
This could be handle with PHP, is there any CI way?
It should be any I think... (if it didn't)
