Something I want to do: Make a digital photo shelf

I want to do this:

Pictures of child #1	Pictures of child #2	Pictures of child #3	Pictures of child #4	Pictures of child #5
		SHELF

But I'm too cheap cautious to buy five photo frames just yet. I'm waiting for them to come in a multi-pack at Costco for $20 a piece...

The goal is to yield a shelf with a photos of each child in their own digital photo frame. This way, if one child has billions and billions of baby pictures, but another has but three, the three would take up as much "visual space" on our wall as the billions.

Paying for five frames isn't the only hurdle to cross. I'm still trying to figure out an elegant way to power the frames. I need to find a safe, ventilated, discreet way to hide power strip and five transformers...
