Optimizing Images

Optimization is the process of fine-tuning your images for use on the Web and minimizing the time it takes for the images todownload. You can use the optimization settings in the Picture Properties panel and the file size information in the Optimize Image editor to keep track of and adjust download time while maintaining image quality. See Choosing an Image Format for information on image file types supported. You can optimize your images in 2 ways:

  • Select a common, predefined setting for basic optimization.
  • Preview the image in different file formats and with different file attributes for advanced image optimization.

You may choose (Not optimized) from the Settings drop-down list if you prefer not to optimize your image.

To control the image format using standard settings:

  1. In Page view, click on the image you want to optimize.
