Upgrade to 4.3.1 is hiding all .jpg images on website

Hi, I upgraded my wordpress site to 4.3.1 and now none of my .jpg images are visible. I read previous posts and this issue was supposed to be resolved from version 4.3. The image appears in the editor, but not during runtime.

I tested this upgrade on my localhost with no issue, but learned of this problem after I went live.

Any recommendations on how I can fix this problem would be greatly appreciated!

Thanks,
Patricia
