"where" depends on the field and table names, table logos and field logo
and thumb is a module for getting a thumbnail of the picture
def thumb(
> from gluon import current
>
import os
> from PIL import Image
> request = current.request
> start = len(where)+1
> end = len(where)+3
> img = Image.open('%suploads/%s/%s/%s' % (request.folder, where,
> image[start:end], image))
> img.thumbnail((nx, ny), Image.ANTIALIAS)
> root, ext = os.path.splitext(image)
> thumb = '%s_%s_%sx%s%s' % (root, name, nx, ny, ext)
> img.save('%suploads/%s/%s/%s' % (request.folder, where,
