I have had disappearing images in documents that have been revised since 
the start of LO, but never tried the export to pdf until the 
disappearing was fixed to notice if they had printed.
Once was when EPS vector images were no longer working, resolved by 
converting to PDF.
Once when LO change the image anchoring, found that the images hadn't 
disappeared, just jumped away, even off the page.
I have a vague recollection of your experience with resizing the frame, 
I no longer have any images in frames so may be that was the reason.
If you save a copy of the document and delete everything either side of 
the pages with the images, are the images still 'gone' but export to PDF.
If you delete the frame is the image also gone (fails to print).
If you then insert the images without them being in a frame does this 
avoid the disappearing.

LO 25.2.1.2 in Windows 11.
The book has 72 images in 13 Chapters, all B&W .png images of a 
technical nature. All were inserted in the same manner: each inside a 
frame containing the image and beneath it, a caption "Figure x.x: some 
text". They are all embedded and not linked.
This book has gone through several iterations over the years without 
problem but the revisions I made this year (3 of them - PaperBack, 
HardCover, LargePrint) all suffer from the same problem. Fortunately, 
the pdf's exported from the odt files are good.
Two of the images, Figures 7.6 and 7.7, are not displayed when I open 
the odt file. The frames are there, correctly sized, no image, the 
caption appearing at the top of the frame.
At first, I tried re-inserting the two images but then each appeared 
twice, so I figured that they were not missing but only hidden. 
Subsequently, I find that if I slightly resize the frame using one of 
its handles to twitch it either slightly taller or shorter, the lost 
image comes back.
Saving the file, closing and re-opening causes these two images to 
disappear again.
Most curiously, if I open the odt file, leave the Figs 7.6 and 7.7 in 
their 'disappeared' state, export the file to pdf, as soon as I hit 
the final 'export' button, the two images jump back into view. The 
exported pdf correctly shows all images.
When I look at the parameters of the frames and the images, I can see 
nothing which distinguishes Figs 7.6 and 7.7 from any of the other 70 
images in the book.
Can anybody shed any light on where to look to see what distinguishes 
these two from the rest so that I can rely on their visual presence 
when the file is opened?
Thank you.
