Exporting to docx cause a similar issue: no picture available (red 'x').
At this point the problem is blocking.

I can always repro the issue when a zoom reduction is applied to the image.
I found no workaround.

What is your full image path and exported PDF file path? Does 1.5.0-dev fix this? In my quick test, it seems images can be included in the exported PDF.

@abnerlee please, first of all try applying 80% zoom to any of your images.
After applying the zoom, the image is not exported anymore.
