I'll help - since this seemingly took me 6 months to master.
Go to imgur.com, click "new post" at the top left hand order, click browse, upload your GIF from your GIF library, hover over the GIF and click on the down arrow, select "get share links", copy link under BBCode (Forums) and paste it in here...

I'd love to know what website people use to fill their GIF library though. I just repost ones I save off this board....which is kinda lame.
EDIT - hold F I take the long way around! I could never get the thing or the unclick this box thing to work consistently.
