I submitted I Can Has Cheezburger 1.1.1 to the app store. It has two fixes and no new features. I’ve changed the swipe action to work the way it did in the original version: I only detect horizontal movement.
In version 1.1 I also checked that vertical motion is less than a minimum amount. As a side effect, it prevented a swipe from being recognized if the swipe is done at an angle, and I got a lot of reports that swiping no longer worked.
I also fixed another bug which could cause the picture to be positioned and sized incorrectly if you rotate the screen while zoomed in. I now reset to normal size before rotating.
