When a raw URL with no markup (e.g. http://www.sucs.org/~cmckenna/photos/quizes/tq2012/July/Jun03key.png ) ends in .png, .jpg, .svg or .gif [capitalisation variants not tested] but does not work (e.g. it gives a 404 error) then only the filename portion of the URL (Jun03key.png in this example) is displayed in the visual editor. Visual editor cannot then edit this URL to correct it, meaning that typos, etc cannot be corrected without using the source editor.

Links to other image formats (e.g. tif), html pages, .txt files and pdf files, and all urls enclosed in single bracket markup work as expected and are editable in the Visual editor. See https://en.wikipedia.org/w/index.php?title=User:Thryduulf/sandbox2&oldid=563642435 for my sandbox testing.

This is not unlikely related to bug 51092 in some way.
