Sharing photos from your iOS device over email is great, until you run into the built-in limitation that prevents selecting over 5 photos. This means that if you have a large number of photos to send via email, the iPhone will force you to send them in several emails with 5 attachments each.
If your device is jailbroken then a new tweak called MailUnlimitedPhotos can solve that problem for you, as it allows users to send multiple photos at once from their iOS device. Say for instance you’ve just gotten back from a vacation and you are looking forward to emailing the photos from the trip to your family and friends. However you are only allowed to send five photos at a time from the Photos app, so you are forced to send them separately. This not only makes the process lengthy but it will also flood your recipients inbox’s. MailUnlimitedPhotos removes this pointless restriction and enables you to attach as many photos as you want to a single email.
MailUnlimitedPhotos is available in Cydia for free. And it is compatible with all Jailbroken devices running iOS7+
