And now it seems to be working. How odd!

@jrawly, I think that change was still propagating and your browser cache have not been updated on that moment that the images have not been displaying properly.

General info about browser cache:

In order to speed up web browsing, web browsers are designed to download web pages and store them locally on your computer's hard drive in an area called "cache". Browser cache (also know as Internet cache) contains records of every item you have viewed or downloaded while Internet surfing. So when you visit the same page for a second time, the browser speeds up display time by loading the page locally from cache instead of downloading everything again.

Although storing Internet cache makes web browser faster as it usually takes your computer less time to display a web page when it can open page's elements or even the entire page from your local Temporary Internet Files folder, you sometimes want to overrule the browser cache, for example to see changes you made to a webpage you just uploaded.

In the future when this will happen again, I suggest that you do a force refresh by pressing CTRL-F5 which will do a non-cached refresh, while F5, CTRL-R, and Refresh button will do a cached refresh. The browser will not retrieve the latest information from the server, unless you perform a force refresh CTRL-F5.

Chrome documentation states that Ctrl+F5 or Shift+F5 should do "Reloads your current page, ignoring cached content."

I hope this helps.

Ctrl-Shift-R also does a non-cache refresh in Chrome and Firefox
