/**
* Actually uploads the file, and act on it according to the set processing class variables
*
* This function copies the uploaded file to the given location, eventually performing actions on it.
* Typically, you can call {@link process} several times for the same file,
* for instance to create a resized image and a thumbnail of the same file.
* The original uploaded file remains intact in its temporary location, so you can use {@link process} several times.
* You will be able to delete the uploaded file with {@link clean} when you have finished all your {@link process} calls.
*
* According to the processing class variables set in the calling file, the file can be renamed,
* and if it is an image, can be resized or converted.
*
* When the processing is completed, and the file copied to its new location, the
* processing class variables will be reset to their default value.
* This allows you to set new properties, and perform another {@link process} on the same uploaded file
*
* If the function is called with a null or empty argument, then it will return the content of the picture
*
* It will set {@link processed} (and {@link error} is an error occurred)
*
* @access public
* @param string $server_path Optional path location of the uploaded file, with an ending slash
