So far I've found that image format can be 256 color (8 bit) .bmp. Will not show if it's in 24 bit format as the FSX screen capture is. (Edit-16bit-444 and 32bit-888 also work if you want to preserve detail)
I used the Dxtbmp utility to flip the image and then save as Extended Bmp>Extended 256 color. Make sure that Mip maps--'include
