Have a look at my "TSEuImageEditor", which uses FreeImage library to load jpegs.

In file TSLibrary_DraWwnd.ew in procedure set_image() image is loaded like this:

    Main_freeimage_image = fiLoadImage (filename)
    Main_bitmap = fiCreateDIB (Main_freeimage_image)

Main_bitmap is HBITMAP

I think HBITMAP can be created also with cximage library.
