I would like to use are particular font (Gils Sans, however, I am not sure how to load it into my Photoshop5.5 program. Do I simply make a folder in the photoshop folder and label it, "Fonts"? Should there already be an existing font folder there? Do I have to download Adobe Type Manager? I also have a question as to what exactly is the difference between Adobe Type Fonts and True Fonts?
