Directly uploading GIFs without referencing a URL is not possible with the current version of vBulletin being used. Users can upload GIFs as attachments, but they must link to these attachments to display them inline. Some users have experimented with making attachments "Parentless" to retain visibility even after canceling a post, but this may lead to issues like invalid attachments. There is speculation about future updates that might improve GIF functionality, but no definitive solutions are available at this time. Overall, the current method requires workarounds to share GIFs effectively.
