As mentioned in irc, you're trying to execute the image as a command,
from the python os.system documentation:
os.system(command)
Execute the command (a string) in a subshell. This is implemented
by calling the Standard C function system(), and has the same
limitations. Changes to sys.stdin, etc. are not reflected in the
environment of the executed command.
I believe you just want
db(db.comment.title==session.new_image_title).update(newimage =
'applications/turtle_art_images/uplodates/%s.png' %
session.new_image[:-3])
