Can you please add a new patch to sort the includes?

Is it possible to use fit_image_load() here instead of writing a new function? I suppose not, since you need to load the data from an external source. Can we at least put the code to read the details into image.c, in a new function? Then this file can call it - it can return a struct with the info, or a few parameters, perhaps.
Also please see spl_load_simple_fit() where you might find some common code.
