Web graphics are computer display images or animated motion pictures that can be displayed on Web sites. They can incorporate animated GIFs, banners, bars, backgrounds, interfaces, page elements, and clip art.

Browsers usually support only a few graphic formats like GIF, JPG, and PNG. If you try to use WMF or EPS formats most people won't be able to view your graphics, because browsers can't display these formats without installing other software like a plugin.
