    Post readable right-side-up images and perhaps someone will respond.

    Even then, many helpers will not respond. Your best policy (and the PF standard!) is to type out the problem and type out the solution, reserving images for diagrams and the like. It requires a bit of extra effort from you, but that is compensation for the effort you ask from helpers.
