I want to add my experiences to this thread.
Issue with 2013, though I am sure it did all work for a while then suddenly did not. Updated to 2016 today and problem still persists:(.
I have 12 images on my reports, all images display fine in report or layout view.
In print preview images 1,2 and 10 generally show, sometimes in other peoples reports only images 1 and 2 will display and all at a low resolution also. All images are JPEG approx 3mb each.
However my template report which shows a lower size JPEG image (approx 177kb each) for each image that is needed, 11 images will display in print preview, sometimes all 12, this fluctuates when switching from report view to print preview but generally all
11 will display:/.
When exporting as pdf, i get exactly the same results as printing.
Please MS get this sorted I spent many, many hours on learnng and building my DB for my studies and new career only to find that I have no way to present my studies for my observational module.
Gonna try linking images in report again, last time they just disappeared.
