I understand that. However, if you read the other postings, you will see that some people do, and other people don't. That's the puzzle. Moreover, I just posted a screenshot that shows exactly what I see. In addition, before posting my first post, I tried three different sizes of linked images, and I obtained exactly the same results in each case.
If you have some possible explanation for why this phenomenon sometimes appears and sometimes doesn't, that would be helpful. However, it isn't productive for us to debate whether the phenomenon exists, when I have both described it and shown it concretely with a screen shot.
