Mike,
Here are my answers w/regard to Rena's suggestions/questions for Philippe -
- The picture came from my computer, not the Internet. And I would usually 'copy & paste' it (.JPG file at 109KB) to every new project item within the same file.
2. I only found this fix-it thread, as of 3/3/2017.
3. Yes, the issue of 'no photo image being displayed' occurs in all of my 8 files & when I 'save-as' file #8 the issue was still evident.
4. Here is a screenshot of the correct image being displayed (my OK2BG logo in the lower right-hand corner) when I print the file -
(As I mentioned in my previous response - When I go to View > Graphics Manager > (locate one of the images not displaying & click the side toggle) > Details // The .jpg image displays there, okay.)

- Here is a screenshot of the image not displaying in my file -
And you can see that all the images are blank in the mini-icons of my 7 other postcards on the left-side panel, except for the last one on the bottom, which I just added to see if it might also disappear at some point.

- I will send you a copy of the problem file via your private message board.
To your questions -
- The steps I took when I first encountered the problem was that I simply opened the file & there it was, or was not. As I mentioned in my previous thread, the only other different thing I did before I closed the file was to make/print pdf files of each
postcard.
- I checked for Office updates (inside Publisher) & it said 'You're up to date! - The latest version of Office is installed on your computer' at these coordinates - File > Account > Office Updates > (toggle for) 'Update Now'
I thought I read somebody's suggestion about checking recent updates -
When I check for any recent updates at - Control Panel > (type 'updates' in the Search Field) > Programs & Features > View installed updates > there were only 2 recent updates on 2/22/2017 w/regard to a Security Update for Adobe Flash Player & an update
for Adobe Acrobat Reader DC.
- I have Windows 10 > Microsoft Office Home & Business 2016 aka Publisher 2016 version 16.0.7766.2060 installed on 3/3/2017 (not sure what that date means, maybe a hidden update?!)
Other than that...I still like Publisher, but am hesitant to do any further work in my files and/or I do not want to replace all 500 of the errant images across all my file/projects.
I will wait to hear from you.
Thanks!
Jack
