JPEG images (.jpg) are useful on the web because they provide a medium between quality and file size. To publish JPEG images in Flash, move the playback head to the frame you want to publish, and all other frames will be ignored.
The JPEG tab has a couple of options that we have not covered yet with the other image tabs:
If you are creating a JPEG image to later load back into your Flash project dynamically, do not set the Progressive option, because Flash has problems loading progressive JPEGs.
This ends the section covering the Image tabs. The final tab to go over is the QuickTime tab.
