Paint your table any color that floats your boat , I chose a bright teal .

After you let the paint dry ( really let it dry , if it is still tacky your photos will get stuck ) , arrange your photos across the table. you can do this however you like (obviously)...I used photo booth pics but you can use anything really.

After you have put you photos the way you like carefully lay the glass down.This specific table had a piece of fitted glass already with it. If yours does not you can buy a piece of glass from a craft store or even a frame shop , just give them the measurements you need..or you can even do it cheaper and go on a scavenger hunt!
You can even lay resin down instead but that is time consuming and if you've never worked with resin before, a little tricky. I like to use glass because if I want I can always change out the pictures.
