It seems to me as you are trying to copy the the file name variable instead of the actual file.
copy($leftear_name,$move_dir.$leftear_name);
This copies the name of the file you sent to the specified directory.
I think this is what you're looking for.
copy($leftear,$move_dir.$leftear_name);
This copies the file to the directory instead.
When you send a file from a form you will get one variable called whatever you called the form field. This contains the actual file. The variable $xxx_name is just the name of the file.
Check the PHP manual for all the variables involved with file transfers.
