There is a bug with the post editor. Images pasted from other websites from your clipboard will automatically use the [img] tag instead of uploading a copy as an attachment. Please manually save the image, upload it to the site, and then insert it as a thumbnail instead if you experience this.
The [img] should essentially never be used outside of chat. It does not save disk space on the server because we use an image proxy to protect your IP address and to ensure people do not rely on bad third party services like Imgur for image hosting. I hope to have a fix from XF soon. I REALLY WISH THEY'D HOTFIX THIS SO I CAN REMOVE THIS NOTICE.
Already posted this on another thread but worth repeating due to how much it made me laugh first time I watched it, both due to the content of the video...and due to the reactions others had in the comments section
Full disclosure, this is only funny if you are passably versed in /pol/ lore. However if you lack this knowledge simply head down to the comments and you will very quickly be enlightened why this video almost made me puke from laughing so hard
