Apple TV In Business

We are contemplating of using Apple TV in our business. We would like to shows customers our catalogues designs/photos on a TV using Apple TV instead of printing designs.

We have over 12,000 TIF files and all these files are saved on our File Server (Windows). We do not have a mac, all our PCs are Windows 7.

How can I possibly create a slideshow of 12,000 images or even create a small album on a Windows PC and get that album to show on Apple TV? Can I connect Apple TV to a Domain? Think we would be to do this using Home Sharing feature.

Also, will AirPlay feature work, if we are creating something on PhotoShop app on iPad?

And can you please suggest a good comptaible screen for Apple TV?

(I personally use Macbook, iOS devices, but not have used Apple TV yet. But at work it is Windows & iOS)

Thanks for your help.
