I don’t think you can do anything; Imgur itself fucked this up a while ago so that even if you, yourself, have a direct link and it seems to work, everyone else gets sent to the page with the ads, and not the direct image.

But have you tried the proper format of making a linked with an exclamation mark ahead of it?

^ that was done with the embedding markup and the link you provided that was in .gif format. It’s not animating tho.
