Don't forget that it's $239.88 USD for a year on Photoshop (it can be paid monthly). I once had the exe for earlier versions of Photoshop but they don't work anymore (sucks because I paid the full 700 for it), but GIMP is at least FREE. There are other programs but I stick with Photoshop due to familiarity and it's a good program, and cheaper for the yearly plan than buying the program outright (which I would do again if the option was there) as they used to do. Anyways I'm rambling and skinning isn't hard, you just have to find out how things work and you'll figure it out. I'd first look in the Downloads section for a template which you can use (or if somebody has one if you ask) to start your project. If not you may have to make your own if one doesn't exist, which is a project on its own. There are plenty of tutorials online in how to use the programs that you may pick. Note there are other programs, which may be around as well, as well as picking our brains of those who do skinning on this site.
