I have a dozen or so Word Online docs in Dropbox, each with a single jpeg image inserted from my local computer.
These documents were last seen with the image successfully inserted.
After coming back to these Word Online documents after some weeks, only some of the inserted images are now displaying, both in the document thumbnail and when the file is opened in Word Online.
For the other Word Online documents, the inserted image does not display in the thumbnail and appears to be loading continuously when the file is opened in Word Online and never displays. For these, when I hover over the apparently loading image, there is a tooltip type message "Inserting Picture..."
The same issue is replicated accessing these files on DropBox on two different computers.
I cannot be certain I ever saw the images displayed in the affected files after the first time I closed the doc.
Does anyone have any hints to avoid this re-occurring?
