The plugin affects the image while it is uploaded. Straight 
after it is uploaded, all Exif data will be removed from the image. 
There is no original image left, nor made a backup. 
This plugin uses the removal service of http://www.exif-remove.de .
ATTENTION: This service is intended to save your privacy and 
should not be used for illegal activity like copyright violations. 
You are allowed to use this service for legal activity only, 
this includes that you must have the explicit permission 
from the holder of rights to clean a file with this plugin! 
As of now, to prevent abuse, the eventually existing 
copyright information will be kept inside the cleaned image. 
To disable this plugin temporarily, just deactivate it within the 
Exif-Remove settings menu. Thanks.
