[Image-SIG] Image.resize problem

[David Dahl]

For some reason Image.resize will not work for me. Here is my method:

import Image

def resize_image(self,infile,outfile):
         im = Image.open(infile)
         size = 800, 600
         im.resize(size)
         im.save(outfile,'JPEG' )


The files is written, but it is the same size as the original file.  
The thumbnail function works fine, maybe that is all I need? What is  
the real difference between resize() and thumbnail()?


Best Regards,

David
