Same experience here. As of late yesterday 21 February 2019, the attached images started showing themselves as clickable links to JPEG, JPG files.
Speypages is the only website where I have experienced this.
Windows 10 version 1809
Opera 64-bit version 58.0.3135.65 (also based on the Chromium engine used by Chrome and soon to form the basis for Microsoft's next web browser)
Would guess that there are issues with one (or more) of the servers as the site strikes me as being slower to load.
P.S. The latest version of Windows 10 is a real dawg. Please note the constraint and self-imposed discipline I used in describing in version 1809. For the first time in years, I have had thoughts of going for a Unix-based OS like Linux.
Science is not common sense. Much of it is devoted to a systematic documentation of what we do not know and understand.
