I’ve found that when I post a link to one of my games on its own line (creating a onebox), the image is often broken. Here’s an example screenshot: https://imgur.com/a/kVTEC. In two instances I’ve had the image load properly when I initially posted it, then later it failed to load.
Furthermore, the frame of the broken image overlaps with text and intersects the frame of the onebox.
I’m going to experiment on this thread to see if I can come up with repro steps.
The onebox is now displaying like this for me: https://imgur.com/a/VkZQj , with no image (not even a broken one). I’m back on the computer I originally made the post from.
I just noticed that the same link displays the image correctly in your other thread. Perhaps there is a bug when the forum software tries to save a local copy of the image with the same filename as an existing image?
