AHA! I figured it out!
I had the same problem with a jpeg that was perfectly square. The problem lies in the function starting at line 30.

            //decide which is the % of shrinkage to use
            if ($shrinkx<$shrinky){
                $ratio=$shrinkx;
            }elseif($shrinky<$shrinkx){
                $ratio=$shrinky;
            }

What's happening is that since it's square, the ratios are the same and there's no condition to handle it so it sets $ratio to 0

The fix is simple

            //decide which is the % of shrinkage to use
            if ($shrinkx<$shrinky){
                $ratio=$shrinkx;
            }elseif($shrinky<$shrinkx){
                $ratio=$shrinky;
            }else{
		$ratio=$shrinkx;
            }

Just set ratio to one of the 2 shrink values.

Hope this helps you all out!
