A family of Microsoft word processing software products for creating web, email, and print documents.
Are you sure it is a file type that Office can handle, like JPG? (I assume it is, but have to ask).
Exactly how are you inserting these images into the files? Describe the process, step by step so we can try to recreate it.
Could you upload an example file to OneDrive and give us a Share>Edit link to the file so we can play with it. Thanks.
Try going in to File menu > Options Command >Advanced option > Show Document Content section. Make sure there is no check mark next to "Show Picture Placeholders". I doubt this will help also, because placeholders normally take up the same amount of space as the image will.
That capture of yours shows a "diamond" of arrows hanging off the bottom of the image placeholder. I do not recall seeing anything exactly like that. I am interested to hear what the solution will be.
