can you view photos on a television from an I-Phone 4s

You can purchase an Apple tv to stream your whole phone to your tv or you can purchase an adapter.

Adapter: http://store.apple.com/us/product/MD826ZM/A/lightning-digital-av-adapter

And if you are going to be buying one id have to recommend going with the Apple TV as it has many more features and is a better buy than the adapter.

Two ways:
