The app PhotoSync by touchbyte GmbH is universal. Check the developer, there are many apps with almost identical names. One purchase puts it on all your iOS devices (that use the same account). There is a free computer side client also, though it is not necessary it does make things easier.
The app uses wi-fi when it can, when all devices are on the same wi-fi network. It will attempt to use Bluetooth if no wi-fi is available.
This is what I use. There are a number of other apps with similar function and various prices, including free.
There are numerous other ways to send, share, or sync photos between iOS, computer, and other devices. Some suggestions are.
DropBox
Photo Stream (shared)
Photo sharing websites like Flickr, Photobucket, or Picasa.

If Bluetooth is not vital to what you are doing, you may want to explore some of them.
