did you create an image with the admin interface, as shown on p. 56?
If you did not, then the select on line 6 would return NO records, and
therefore select()[0] would create an
index out of range.
You can check / change this by re-writing the select in the show() procedure
to something like this (I have not tried, so it might not be quite right):
def show():
images = db(db.image.id == request.args[0]).select()
if len(images) < 1:
session.flash = T('No images to show!')
return dict()
image = images[0]
# the rest as is....
