Here are the steps:
- Take some new pictures on the Android device.
- Run Bump on the Android and on your iPad, and set the Android to share your new pictures.
- Bump the devices. The iPad automatically places the new pictures into Photo Stream, which means they should also be in iPhoto almost immediately.
[crarko adds: Bump is a very useful app. It runs on iPhone as well; I didn't know there was an Android version. This is a clever use for it.]
