    <p>Whenever I try to download a jpeg attachment from an e-mail half of the jpegs come out corrupt. I'm sending them all the exact same way from a phone, but there are times when the attachments are bigger than the actual size of the picture. Here's the code I have.. am i downloading it incorrectly?</p> <pre><code>#!/usr/bin/python from itertools import izip, cycle import os import imaplib import email import getpass import re import mimetypes import base64 import grp import shutil import time pattern_uid = re.compile('\d+ \(UID (?P&lt;uid&gt;\d+)\)') class pygmail: def __init__(self): self.IMAP_SERVER='imap.gmail.com' self.IMAP_PORT=993 self.M = None self.response = None self.mailboxes = [] def login(self, username, password): self.M = imaplib.IMAP4_SSL(self.IMAP_SERVER, self.IMAP_PORT) rc, self.response = self.M.login(username, password) return rc def logout(self): self.M.logout() def get_mailboxes(self): rc, self.response = self.M.list() for item in self.response: self.mailboxes.append(item.split()[-1]) return rc #creating/renaming/deleting new mail folder def create_mailbox(self, mailbox): rc, self.response = self.M.create(mailbox) return rc def parse_uid(self, data): match = pattern_uid.match(data) return match.group('uid') #get the emails with attachments, create a folder, send them over def get_attachments(self, folder='Inbox'): name_pat = re.compile('name=\".*\"') self.M.select(folder) subjectSearch = "Whiteboard Image -- Application in progress --" resp, data = self.M.search(None, '(UNSEEN SUBJECT "%s")' % subjectSearch) counter = 0 detach_dir = '.' for num in data[0].split(): resp, data = self.M.fetch(num, '(RFC822)') mail = email.message_from_string(data[0][1]) #self.M.store(num, '+FLAGS', r'(\Deleted)') # walk through individual mails, looking for attachment of JPG type for part in mail.walk(): if part.is_multipart(): continue if part.get_content_type() == 'text/plain': body = "\n" + part.get_payload() + "\n" if part.get_content_maintype() != 'image': continue file_type = part.get_content_type().split('/')[1] if not file_type: file_type = 'jpg' filename = part.get_filename() if not filename: filename = name_pat.findall(part.get('Content-Type'))[0][6:-1] print filename #PARSING BODY OF EMAIL destFolder = albumHeader = ' ' if body: word_list = body.split() for i in range(len(word_list)): if word_list[i] == 'DestFolder:': tmpWord = word_list[i].split(":") destFolder = tmpWord[1] elif word_list[i] == 'AlbumHeader:': tmpWord = word_list[i].split(":") folderFlag = word_list[i] #download the attachments from email to the designated directory att_path = os.path.join(detach_dir, filename) #Check if its already there if not os.path.isfile(att_path) : fp = open(att_path, 'wb') temp = part.get_payload(decode=True) fp.write(temp) fp.close() cmd = "chmod -R 755 ." os.system(cmd) counter = counter + 1 #MAIN PROGRAM #login to email, print login status to terminal g = pygmail() g.login('username', 'password') print g.response g.get_attachments() </code></pre>

    1. COI don't see anything wrong with how you're saving the attachment payload; the code works for me over multiple runs using different sized JPEGs, mixed with other attachments. Have you downloaded the JPEGs from the Gmail account manually to rule out corruption on the phone, or on the upload side?

    2. COYou might want to check out the [IMAPClient](http://imapclient.freshfoo.com/) library, should save you quite a bit of headache :)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
