I wrote up an internal how-to/policy for the company I work for, which had text and some images that weren’t showing up. Googling and looking through the options for the document didn’t help.
After going through it some more, I found that you need to check in all items [in the Document Center] before it becomes viewable by others. What threw me off was that my department could see it, but not other departments.
The Document Check In Page followed with this message:
Other users will not see your changes until you check in. Specify options for checking in this document.
Hope this tip helps.
