At least the posts that contain multiple URLs to pictures (and users trying to view them, of course) .
Specifically in this case, links to commons.wikimedia.org, when put on line by itself, should show the image (and other metadata like filename). And they do while editing in preview pane, and (it seems) for a few seconds after the post is submitted, but after several seconds most of the links lose images.
Where on the platform does it happen?
in such post with multiple images being displayed. Here is an example post where it happens:
Here is how it looks during editing (all 12 images are visible in preview pane):
I’ve encountered this issue on numerous occasions. For the most part, I’ve been employing a workaround of linking instead to the same image on the OSM Wiki (which automatically fetches images from Commons). I don’t know why the OSM Wiki is able to display the images more reliably than its source, but it’s an interesting data point.
Of course. I hoped more for a chance that only articles actually having inline images would be re-processed.
But I have no idea how hard it is to find (e.g. selecting with multiline regex ^(https?|File): ?)
I do not know, but many (if not every) posts which had more than 1 image that I encountered in the past had this problem (those with only 1 image IIRC worked fine, at least in most cases). But if it is too complicated, I understand it’s likely not worth a trouble.
I’ve just noticed a fresh post (9 hours old at the moment), where image is not rendered in Discourse. Force-refreshing or trying other browser does not help either; but the linked commons image opens normally when clicked on. It is in the middle of this post: Clarification about the use of Key:brewery - #4 by osmuser63783
Can you @nukeador tell if that is the same problem, or a new one?
does not denote a JPG image; it’s actually a HTML page containing the desired image. To link to an actual image, one has to select one of image previews, linked in fine print immediately below the image, such as
…which can be embedded as an image:
