7. Click the lower-left section to select it. Open the Preset drop-down list box and select JPEG
Medium if it is not already. Click the lower-right section and change it to the JPEG Low preset.

seconds to download. Click in the lower-left preview window, and then click the Preview In
Browser button along the lower edge of the Save For Web dialog box. Your default web browser
program launches and displays the image along with suggested HTML code and image statistics
