Why don't you use good quality JPG thumbnails (72 to 150dpi)for your users to browse. When they click on a desired image it would link them to the 300 - 600 dpi download file. Since I develop training materials and have had to utilize high quality photographic images in my training materials I can see how they would want 300dpi as a minimum for printing.
