Relax. It looks fine. The residue on the side of the bucket indicates you had some krausen that has since fallen back into the beer. If you are really nervous, pull a sample and take a gravity reading.
Don't make the mistake of equating airlock bubbles with fermentation. CO2 may have been escaping from around the lid, or around the sides of the airlock. The only way to determine if your beer is fermenting is by taking gravity readings and observing changes in the specific gravity.
Tell that someone to leave your beer alone.
