      The content type needs to be checked in the Response property, not the Request property, because you need to inspect the images that are being returned and switch them if the browser is a mobile device. The browser information is sent during the request, therefore, you need to check that in the Request property.

    The 2nd selection is wrong => The application must support image format conversions from .bmp to .jpeg for mobile devices.

    So should be:

    normalFormat = “image/bmp”

      The original answer is correct. The normalFormat variable indicates the non-mobile-return-image format. If the image being returned is bmp, then it should be converted to the “normal format” which is png.
