Displaying alternate, low-resolution images

If you work with PDF documents which contain high-resolution images, you may want Adobe Acrobat to display these images faster. You can do this by clicking the Speed Up Image Display button, provided that the images in your PDF document have alter­nate images at a lower resolution. If they don't, you can easily add alternate images using an Action List.
