This is intended to be the first of a series of turorials on how to create skins/templates with the GIMP (GNU Image Manipulation Program) For those not in the know, GIMP is a free program similar in function to Photoshop or Paint Shop Pro. There are versions for Windows, Linux and Mac/Unix.
I also recently made a short (although not very in-depth) tutorial for creating nose art from period photos using GIMP.
Comments, suggestions, requests, and corrections all welcome!
All my tutorials can now be found at FlightSimGuides.com.
