Jang,
If you are working from servers, Kenneth's suggestion for using EPS (good idea) may or may not help; it depends upon your connection to the servers.
If you do not need to see the images as you scroll through, say for correcting pagination or just proofreading text, you can turn off the display of the images by selecting View > Options and the CLEAR the Graphics option but SELECT the Borders on Objects option. Frame will then display the borders of the anchored frames but not their content. If you arrive at a page at which you need to see the image, then you can turn ON the display of the graphics.
Good luck,
Van
