Hi, it seems your minimum resolution perameter doesn’t work properly. If you specify the minimum resolution to be 800x1200 the customer should be able to upload an image with a total of 960 000 pixels, however the customers length or width must match the 800x1200 requirements. For instance a customer cannot upload an image with 1200x800, or even 900x1100. It should work by the total amount of pixel data. Am I wrong about this?
