When creating shape tags (and shape tag scripts), try to use a resolution divisible by 8. If that is not possible, use a resolution that is divisible by 4, or at least 2 = even numbers. Several codecs are not able to handle resolutions with odd numbers, and some codecs even require resolutions to be multiples of 8×8 blocks.
