Ok, so this is what I’m gathering:
On the Discourse forum @ meta.discourse.org, the issue we’re having here doesn’t exist on their’s. The images on their polls work fine. Meaning that it’s just something with this forum and the poll settings/options.
The last option in the poll is the GIF you see on the bottom spinning. It works just fine outside the poll.
One of the staff on that forum recommended getting an admin to update the forum to the most recent version.
