SP 2013 Images not rendering

Question

Hey all,
I've got a REALLY weird SharePoint 2013 problem that I need some help with.  If my users go to Cogwheel -> Add a page and add a publishing page, they will type some text and add some images...however, when they save the page, the images all disappear.
I take a look at the source code and, sure enough, the <img> tag is there, however the src property disappears when we save the page.  No matter what I do, I cannot get the page to accept the "src" property of the image.  The images
appear initially right when they are added while in the "edit" screen, however, again once saved, they disappear.
We are not running any customizations or anything and the problem does not appear in our test environment or on any subsites of our live environment...just on the main site of live.
Does anyone have any ideas?

Hi,
From your description, when you click save and try to add pictures to a page the SRC property disappears.
<p>
<img src="http://****/*.jpg" alt=""/>
</p>
<p>
<img src="/document_lib/*.jpg" alt="" />
</p>
First of all, let’s try to narrow down the issue and check whether it is client side problem. You may check the HTTP traffic when you click Save with network trace tools such as Fiddler.
A normal Save would include:
1. A POST HTTP request where you can see inserted IMG node under MainPlaceHolder.
2. And the POST request get the responses of HTTP 302 Found which redirect you to the sitepage.
Please help to check:
Does the whole IMG with SRC property get posted to the server?
What is the response of  POST request?
