If you’ve ever tried to e-mail out some of your pictures from the iOS Photos app you’ve probably noticed that the e-mail option disappears if you select more than five photos. While this still hasn’t been addressed in iOS 7, the good news is there’s a quick and fairly easy way to work around this limitation: Simply use the iOS clipboard. Go into the Photos app, select as many photos as you would like to share, and then choose “Copy” from the sharing menu. You can then switch over to the iOS Mail app, start composing a new message, and paste your photos in by tapping and holding in an empty area of the message and selecting “Paste” from the pop-up menu that appears.
There doesn’t seem to be any practical limit to how many photos you can share via the clipboard, but keep in mind that just because you can select dozens of photos doesn’t mean that it’s a good idea to send them out in a single e-mail message at full size—many mail servers will reject e-mails with excessively large attachments. The good news is that iOS Mail app will offer you to reduce the size of your attached photos for you before sending your message, so sending a large number of photos via e-mail is definitely an option if you’re willing to scale them down.
