This is a 4 year old thread....just in case.
Ha, thanks!
That's funny. Looks like I unintentionally revived it. But how?
2-3 days ago, a list of new posts included an intriguing (for me) title, rather similar to "What is this white line." I opened it and it contained a description of the problem, but no images. The post had only one reply, by Mark D Segal, who simple noted that the pictures are missing.
A day or two later, I remembered it and thought, hmmm, the OP must have added pictures by now, let me check. It was nowhere to be found among recent posts, so I tried searching for "white line" in titles, and got this thread.
Or maybe someone was trying to gaslight me
