Images in HTML Documents Images in HTML Documents Images are easily added to HTML documents.
Images can contain meaningful content or be used solely for decoration.
In either case, their use should be weighed against the amount of time that they slow the downloading of the page. If this is done, it's recommended that the same graphic be re-used throughout the document. This is both because the browser only has to download it the first time so page-load time is kept short and because repeating the same element adds visual continuity to the page.
