I seemed to have overlooked this thread.
As Colonel Ingus said, Grab an older copy of photoshop I'm sure there is a 30 day trial thopugh if your new to graphic editors you may find photoshop a bit bulky and daunting but overall it's the industry standard and the best graphics editor imo.
There are free alternatives that are easier to get along with and I suggest you grab this great program
Gimp 2.2.1. It's free and a very powerfull program and there are plenty of tutorials on their homepage to get you started.
Another excellent free program is
Inkscape 0.43 you can download that (link Below) although it may be something you'll use in the future rather than now and it also has plenty of tutorials on their homepage. You can download that
Here
If you decide to opt for Photoshop I strongly suggest you give this site a visit
This Site. The site has an abundance of tutorials and this is one of the sites that go into detail on how to use the tools and functions of photoshop rather than the everyday "how to make a flashy signature" and learn nothing in the process. :classic:
