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.
