Websites use graphics to enhance information, assist navigation, and generally improve the user’s experience. To create those graphics, developers use any number of programs, like the Adobe Creative Suite (Photoshop and Flash have their own topics), the CorelDraw suite, Xara, Gimp, ACDSee, Serif, ULead and others.
