We haven't heard of users having this issue recently. Are you still getting the same message where an image should be, or something else. Any info you can provide, including a link where we can see the problem, would really help.
There are still bug reports of similar issues pertaining to viewing images, like below:
developers.facebook.com/bugs/911831642174059/
Those bug reports seem more nuanced though and shouldn't affect large swaths of sites like the previous bug did.
Thanks,
Alex
