Compressing Images for the Internet with JPEG
The best way to speed up your Web page is to use more image compression. Slow
download speed is often more of a drawback to a Web site than compression arti-
facts (visual irregularities) in images. The Save For Web dialog box of Photoshop and
Photoshop Elements allows you to get the best performance from JPEG images.
Follow these steps to experiment with compression:


  1. Select the Save For Web command from the File menu. The Save For Web dia-
    log box enables you to experiment with compression and color settings for
    images. These settings enable you to find the best compromise between
    image quality and download speed.

  2. Click the monitor color and download rate button.

  3. A pop-up menu appears. Check the settings you want to use. When choosing
    a download rate, remember that many viewers’ modems work much slower
    than they are supposed to work.

  4. Choose how many versions of your image you want to view. You can open
    two- or four-image windows at once; click an image window.

  5. Select a JPEG quality setting for the image window you selected. Do this for
    each window.
