In years past it was complicated to make a presentation. Microsoft sold thick books on just how to do it.
Nowadays all it takes to make a presentation is to create a slideshow for photos,
Nothing beats the iPad to do so.
Even better use Keynote for iPad. Keynote accesses all your photos and makes it easy to sequence them in any order.
Keynote then gives you all the rest of the tools you need in the simplest possible way.
