I took the photos of Hong Kong with the app called Moby Pal. It is available in iPhone/iPad.
You can take one or a few photos and send it by e-mail to a preset address with just a few button press. It is quick and easy.
There is also a "security feature". You take a photo and send it by email with the time and location stamp. If anything happens to you, there is a record of the taxi or location where you took the photo. All this in just a few touches.
A great tool, for travelers and for ladies.
