Hey freedom family,

I recently went on a cruise. One day a staff member came out onto the deck and started taking pictures with an iPhone and they were automatically added to a slideshow being shown on the screen. (No cords)
I was wondering how I could do this? Here's a break down:
1. A photo will be taken with an iPhone.
2. The photo will be automatically added to a slideshow Of all the photos taken
3. This slideshow will be shown on my Mac and output to a screen.
Devices:
iPhone
Mac
Output from Mac such as TV

Any ideas? Usually I could figure out something like this but this time I don't really know. I've read articles but they all cost money.
Any way I could do this for free? Is there an app?

Thanks
