*
* @param string the name of the field
* @param string the path where to store the file. The standard path is APATH.'files/filemanager/'
* @param string a prefix for the filename
* @param boolean zip the file if it not an image and is set to true
* @param array the array contains (maximum width, maximum height, action_string). Possibles values for the action string are: 'NONE', 'CROP', 'RESIZE', 'SCALE'
* @param array the array contains valid mime types
* @return mixed the filename string if upload only a file, an array of filename if upload many files
