Well, Firstly let me say Welcome to the Guild, The Mappiest Place on the Web and secondly to let you know that if you are familiar with the Adobe suite of graphic tools, then there is no better place to get your skills translated into mapping greatness than the Tutorials forum. There are oodles of Photoshop tuts and I believe that there are some that also use Illustrator as well. Have fun and see you in the WIPS
