Reply To: How to Handle Large Image Files in InDesign Without Slowing Down?

What file format are your images? I recently had a situation with lots of what I thought were jpgs slowing things WAY down. I can’t remember whether they were saved as “JPEG 2000” or “Large Document Format”, but as soon as I switched them to normal files (jpg or psd) they were fine. Clearly INDD was having to generate preview thumbnails of very large images every time they were displayed.
