Version: 46.0.2597.32 - Opera is up to date
Update stream: Stable
System: Arch Linux (x86_64; Unknown)
If you click on a date point on one of the plotted lines you should get a popup showing an image for that date. This used to work until a recent Opera update.
Instead, I get a popup that says "Image unavailable on this browser".
Same thing here (debian testing x64, opera-stable 46.0.2597.32), however it also happens on chromium (59.0.3071.104) and on firefox (52.2.0 esr) as well, so I assume it may be some (shared) image library that they all use and does not work properly.
The underlying images have timestamped URLS like this:
and they can be displayed correctly in 'feh', directly from the url.
ftp url above is mangled; many missing underscores; changed by moderator maybe. Conclude nothing from the fact that it doesn't work.
I think this is the problem:
