Konrei-sama, I think he's using the template that Thunder025 made.
brianng88, here's how I did it. First, make the Template layer 1. Place the image you then wish to use on top of that layer which makes it layer 2.
Now set the opacity level of the image you want to use to about 30-40%. Now you can somewhat see the template behind the image.
Now all you need to do is carefully erase parts of the image that cover the areas of the template that shouldn't be covered, leaving only the image to be seen on the barcoded background. Once that is done just reset the opacity level of your image back to 100%.
Let me know if this helps you out at all.
