Accelerator software accelerates Web pages, Web-based email (such as Hotmail, Yahoo, etc.), text (including plain text, HTML, JavaScript), and the most common forms of graphics (most Flash graphics, GIF, animated GIF, and JPEG images). In regard to email that is not Web-based (such as Outlook Express), the Accelerator will speed up embedded HTML images. This can be significant in the case of mass mailings that include embedded GIF, JPEG, or Flash graphics.
