No website is complete without custom graphics.
Graphic design is basically visual problem solving using text and/or graphical elements. The aim is to create something that is pleasing to the eye, and gets the attention of the viewer. But things can't just look cool. They have to work as well. How effective is a great looking restaurant menu if you can't for the life of you find beverages, or it's hard to tell which price is for what?
So what do graphic designers actually do? Certainly most people can name at least a few things, but the graphic design spectrum is perhaps broader than you think. In short, designers create the distinctive elements that identify and separate your business from others, your company "branding".
Designs can be included in brochures, posters, magazine covers, magazine layouts, tickets, business cards, T-shirts, signs, logos, book layouts (typesetting), importing advertisements into a newspaper, website, cd cover, dvd interactivity elements, Internet banners, flash animation, web interfaces, Powerpoint presentations, and more. When your graphics are designed to fit your marketing campaign and are used consistently, your clients will always know when they see anything you publish.
