When I click on a photo a box comes up and in that box you can click on edit a new box comes up and you can resize, flip, or rotate left or right. Then I change the pixels to 750 and the other box fills its self. Then I click out and it asks it you want to save, which you do. That works for me hope it will for you also. This is a couple of pics of a handle that has turned darker on one side than the other.
