I am new here and I would like to know what program do you use to make all of these images and games? Also how much does it cost? Is there a way to get it free? The main reason I would like to get this program and learn how to use it is to be able to help out around here because I really like your work. Thanks for all the help

For the graphics I always use The GIMP (www.gimp.org) that is open source and full of functionalities.
