Last night when I noticed it going a little weird, I checked my browsers network tab in its developer toolset and saw the attempt at loading the image returned a 403 Forbidden error from Imgur. Loading the image myself in its own tab worked fine though as you have found.
This was both with an image in a forum post and with an image added by a browser extension I use that runs when loading RSOF pages where the image is hosted on Imgur, so doesnt seem too specific to something Jagex has done from my observation.
Edit: For those wondering what a 403 Forbidden error means, it means that the the server being communicated with (in this case, Imgur) understood the request from your browser, however it is refusing to fulfill it for some reason (refusing to provide the image content).

Whos-Drsaid: So the issue here is that Imgur no longer allows the loading of images over http, in favour of https.
It should be a one-line change to the forum back-end.Interesting how this happens the same day Chrome rolls out version 68, resulting in areas of the website like the forums displaying a red 'not secure' icon. (something I really hope is on the top of the web team's agenda right now)
