Just a quick phone pic of a photostrip I made using a Photoshop template I designed to use my Instagram photos and turn them into a photobooth strip. Each square is exactly the same sized and spaced evenly, the photos edge is my third photo down and the first one is very light so it's hard to see where the photo ends and the white border is.
If you'd like a copy of the template you can get it here
I apologize for the quick post, but I wanted to get it available before it gets too late.
