Hi, Thanks!...no I dont have a tutorial, but its not too hard..just time. It was just multiple layers for each picture and adjustments to each layer..(opacity, blurs, sizing etc), and lastly a few layers for the fonts. I winged the whole thing and did not save the layered version (pdn file) sorry.
Play around with Paint.net...and once you learn it more and more, you will create something better!
