Banners are advertising images which are displayed on web sites. They function like billboards which viewers can click on, to be instantly transported to your web site. They are usually rectangular in shape, but come in a number of sizes. Banner sizes are measured in two ways: 1) physical size, measured in pixels; and 2) file size, measured in kilometers. If we produce your banners, we will be sure to keep the file sizes small and quick! Banners are often animated to capture the attention of the visitor, and to display a variety of images and information.
