    just wanted to add that the thumbnail image name matters (at least in the current version of web2py). I ended up with this code: 
    
def makeThumbnail(img_name,size=(150,150)):
    try:    
        import os
        from PIL import Image
    except: 
        return
    im=Image.open(request.folder + 'uploads/' + img_name)
    im.thumbnail(size,Image.ANTIALIAS)
    root,ext = os.path.splitext(img_name)
    thumbName='%s_thumb%s' %(root, ext)
    im.save(request.folder + 'uploads/' + thumbName)
    return thumbName

def add():
    form = SQLFORM(db.Item)
    if form.accepts(request.vars, session):
        response.flash = "Item Added"
        row = db(db.Item.id==form.vars.id).select()[0]
        img_name=row.image
        thumb = makeThumbnail(img_name)
        if thumb: row.update_record(image_thumb=thumb)
    elif form.errors:
        response.flash = "Form has errors"
    return dict(form=form)
    Does the thumbnail really need a UUID that is not related to the original image?

Upload Image and make a Thumbnail

This is a method I found to upload an image (into the uploads folder) and then create the thumbnail in the same directory. One good point is that Web2py allocates the filenames so everything can have authorization etc. It requires the Python Image Library installed.
