Maybe something like my grid solver[1] would do. Thumb sizes must be chosen beforehand, but you could specify just 2 classes: one for portrait, one for landscap

Maybe something like my grid solver[1] would do. Thumb sizes must be chosen beforehand, but you could specify just 2 classes: one for portrait, one for landscape.
