Do you add gravestone pictures as photos or documents?
You can do either. If I choose the option Upload Photo, pdf documents will not be visible, but there is still a place to type a description. If I choose the option Upload Document, images and pdf files are available. (Word docs are not available either way). So if you put your gravestone image in a PDF with background information, that would apply here. If you click Create Story, you can upload multiple images and compose text to go with it.
