Not sure if this is really the right forum, but never mind.
I've been looking for a way to display photos on my (non-internet enabled) TV. Tried various things, such as using the TV's USB socket, but with limited success. Anyway, I was round at a friends house, and he showed me his Apple TV.
I don't own anything Apple, so I had never even thought about it, and if you do have an iPad or an iPhone you get extra goodies, but you don't need them to use the product.
All you actually need is a home network, a (switched on) computer, and iTunes running on the computer.
You buy the Apple TV box, at around £80. Plug it into an hdmi (has to be hdmi) socket on your TV, switch the TV to that channel and log the Apple TV on to your network.
What you then do is to tell iTunes which folders (of photos) you wish to share with Apple TV, and they then appear in the Apple TV menu, and display without fuss, either manually or as a slide show. For once, it worked straight out of the box.
Any music or movies that you choose to have in your iTunes library is also instantly available. Plus the usual huge list of internet radio stations, a pretty wide range of podcasts, and of course the ubiquitous YouTube. I have a soundbar attached to the TV, so the sound quality is pretty good. Of course, you can buy/rent stuff too, but I can't see myself doing that.
For me, it is a very useful addition to my home kit. Just thought it was worth mentioning to other Apple-phobes out there.
