'basepath' is a directory. You want "Imagenes['logo.gif']._local_path"

Hello there,

I have an External Method which takes as a parameter the basepath of an
LocalFS Object:

<dtml-let imagen=3D"Imagenes['logo.gif'].basepath"  >
<dtml-call "minipil(imagen)">
</dtml-let>

The external Method is a s follows:

#minipil.py
import Image

def conversion(a):

     im =3D Image.open(a)
     return im.format

Everything is very simple but I get the following error:

 Error Type: IOError
 Error Value: [Errno 13] Permission denied: 'c:\\TestRes\\images'
 where this is the base path for the Local File System

 Can you see anything obvious that I am missing?
 Thanks for your help.
