There's 2 ways to post an Animated GIF in a topic.
Option #1:
If the animated GIF is hosted on the internet just copy and link. Then in the topic / replay you want to post the animated GIF click the "Insert Image" Bulletin Board code so it looks like this (without the spaces)
[ img ] paste link here [ / img ]
Then paste your link in the middle and you are done. The Animated GIF will play in the post.
Option #2:
Upload the GIF to the forum Gallery (See photos attached for the steps 1 to 5): https://forum.e-bodies.org/gallery/sa=selectcat;video=1
Then do the same as Option 1 but remove this part of the link. You only want the https to the gif part of the link in the image area.
