Quite surprised when this forum user know how to adjust width and height but didn't follow your rules that image of the test result that only height should be adjust. In short, know how to change the size but did not follow the rule you stated. Why not give this forum user a chance correct his/her mistake. What I think with this situation is that some didn't even read the entire OP and that cause to not follow the rules.
